Habits and Hustle - Episode 526: Liron Kayvan: Smart Strength Training That Builds Results Without Injury or Burnout
Episode Date: February 5, 2026Lifting heavier, training to exhaustion, and pushing through pain are often labeled as discipline, yet they are some of the fastest ways to stall progress and get injured. The real problem is misunder...standing how intensity and reps actually drive results over time. In this Fitness Friday episode we get into why pushing past your limits is not discipline, what rep ranges actually drive results, and how fitness is increasingly shaping behavior, consistency, and social connection.

Hi guys, it's Tony Robbins. You're listening to Habits and Hustle. Crush it.
Before we dive into today's episode, I first want to thank our sponsor, Therasage.
Their trite panel has become my favorite biohacking thing for healing my body.
It's a portable red light panel that I simply cannot live without.
I literally bring it with me everywhere I go.
And I personally use their red light therapy to help reduce inflammations and places in my body
where honestly, I have pain. You can use it on a sore back, stomach cramps, shoulder, ankle.
Red light therapy is my go-to. Plus, it also has amazing anti-aging benefits, including reducing
signs of fine lines and wrinkles on your face, which I also use it for. I personally use Therisage
trite everywhere at all the time. It's small, it's affordable, it's portable, and it's really
effective. Head over to Therisage.com right now and use code be bold for 15% off. This code
will work sitewide. Again, head over to Therisage, T-H-E-R-A-S-A-G-E dot com and use code

all things fitness today. Are you ready?
I'm ready.
All right.
Thank you for being here.
Thank you.
You're very welcome.
It's nice to have you.
Okay, I got some quick questions for you.
Ready?
Yeah.
Okay.
Body weight exercises versus weights.
What do you think is better?
Body weight has to come first.
You have to be good at body weight first.
There's some situations where you might need to start on weights before if the exercise is hard or injuries, etc.
But most of the time you should be proficient in any type of movement.
the body weight version. So, for example, a push-up versus a bench breast, you should be mastering push-ups
before you bench. Does that make sense? Okay, yes. But in terms of, in terms of like building muscle,
what is more effective? I think you can, again, like, could you build muscle with just body weight,
in your opinion? Absolutely. Absolutely. So like, when I was like a teenager, I started doing body weight
training for like two or three years, my body transformed like that super, super, super, super fast. And then when I
started to lift weights, because I had such a good foundation of movement, the correct movement,
patterns, stabilizer muscles.
I know that's kind of bro science.
I don't know exactly, you know what I mean?
What's bro science?
Stabilizer muscles.
What are you talking about?
Women talk about stabilizing muscles.
No, no, broccience in terms of like, you know, there's not such a thing as a stabilizer muscle
that people really agree on what it is.
But essentially that movement pattern by working your body in a very balanced way that
you get from calisthenics, from body weight exercises, it sets you up for weight lifting
after and I found that people who get good with body weight exercises first can put on muscle
much faster when they do add weights. Gotcha. So that makes sense? It makes sense, but I would say
this. I think that when I think of stabilizing muscles, I think about really strengthening your core
and your balance, which are super important as you age also. Yeah, which I think you probably get more
of with body weight exercises depending on specifically which ones you do. But I'd say you get more of that
with body weight and then you get from free weights after that, free weights and kettlebells,
and then finally, I think, machines.
Yeah, machines are really good for people who have a lot of injury, actually.
Yeah.
Yeah.
I think machines are very good for that because it just works the muscle that you're supposed to work.
And you can also push yourself at a really high level.
So if you want to go super, super heavy safely, machines actually really have their place.
Because say you fail on a machine, what happens?
The stack just drops it on the stack, right?
Right, right.
Not on you.
Right, exactly. So if you're training by yourself, things like Smith machines and cable machines and stuff like that. So I know you were talking about home gyms or friends of mine when they ask me about home gyms, I'm like, look, machines are actually great. If you can find a machine that does a bunch of different stuff, machines are great for the sake of safety and the ability to really, really push yourself to failure without kind of jeopardizing yourself. And also not really like, you don't really need to get form perfect. Like you do like a back squat versus a leg press.
neck press is just way easier.
Yes.
Right?
Form was.
I think that's true.
I also think, though, what do you think about this actually?
Because I know to get stronger and to get results a lot of times it's about progressive overload, right?
Yeah.
But I also think, I was going to say, not but, and I also think that with age and sometimes with injury,
you can't really lift as heavy as maybe you once did.
So, like, I still think that you can still get a really, you could get really good results without killing yourself on like super, super heavy.
Yeah.
Right.
Like, as long as you're doing weight training, I find that to be suitable.
I think intensity is more important than weight.
Weight is an aspect of intensity, but as long as the workout is sufficiently intense.
Well, what I've, why I say this is because when I've worked out with trainers before, they're pushing me to go,
such a, like such a heavy weight capacity. I just don't, my body can't even like do it. And they're
like, no, you can do it. You're strong. You're a badass. You can do it. I'm like, I really actually
cannot do it. Like my glutes are not firing. I have an injury over here. Like,
100% true. And the reason why I'm bringing this up is I think it's really important to really be
discerting A, with who you're working out with and knowing your body. Because just because someone's
screaming in your face that you can do it, you can do it. You can do it.
and you know, like, it's not you being, like, it's not you being a weak, weak ass whatever, right?
It's just that you actually legit cannot do it, right?
And I think that there is like this whole culture now is like lift super, super, super heavy.
No, you're going to lift heavy enough where you can improve, like, on your own strength,
little by little, but don't kill yourself.
That's not the, that's not also the answer.
It's great advice.
Don't kill yourself.
Well, don't kill.
Generally speaking, just generally speaking is good.
Well, I think, yeah, well, just generally speaking.
Well, I was going to say, what is your opinion on this, like, lifting super heavy?
I agree with you 100%.
I mean, the research says anywhere between 5 and 30 reps is good for hypertrophy.
Three?
Five and 30.
No, I heard between 8 and 12.
Right.
So that's the traditional one.
That can lend itself to, look, this is going to be a very big topic of debate between people.
And I'm not giving my personal opinion.
I'm saying that the latest research I've seen is you can get muscular gains from 5 to 30,
as high as 30 reps.
I'd like to see that research because I have not seen that.
I think it's by Andy Galpin, so you can check that out.
But again, essentially.
He says that, because if you're doing 30 reps, that's more endurance than anything else.
Yeah, I know.
That's what we traditionally thought.
I don't personally, because I find it, again, there's personal preference.
There is some personal preference here.
I, depending on the day, so I might go as high as, you know, 25, maybe 30 on certain exercises,
depending on how I feel, right?
Meaning like that would be exciting to me to do 25 reps today.
I feel like I want to do 25 reps.
So I might push myself up to 25 reps.
And then maybe I periodize these things.
You have to, once you get very good at fitness and you've been doing it long, you learn to
listen to your body a little bit more.
But there are times where I want to go super, super heavy.
I want to do five reps or something. And there are times when I want to go higher and there are times
when I want to be in the middle. And I've found that varying things smartly, right, like in a periodized
and structured way, is the best way for me to train because it keeps things fresh and exciting for me.
Well, I think what you're talking about is more muscle confusion. So if someone like me too,
who works out a lot, I can do sometimes 20 reps, sometimes 10 reps, because I do it so often. And I know
kind of like I'm just, I'm doing it more because I'm just quite frankly bored and I'll just
kind of keep it interesting. I would relabel it muscle excitement, not confusion, because confusion,
like, I'm not confused. I know exactly what I'm doing. But what I want is to do something exciting
to me. Like I want to enjoy my workouts and I want to train to get better. So a lot of this also comes
from the fact that I want to be a very well-balanced athlete. So it's not just hypertrophy. I want to be able
to play soccer, which is a very high endurance sport, and then I also want to be able to pick up
a car if I need to. So, you know, I want to be adaptable, right? And I want to be well balanced.
So I train the full, the full rep range. My point is, especially also, there are different muscle
groups that require different rep ranges. So you're generally speaking, generally speaking, your upper
body is going to require less reps and your lower body is going to require more reps.
Glutes, for example, tend to be on the higher rep range.
So they take mostly because they're slow twitch muscle fibers.
So generally you need more reps with glutes.
Again, this is not like just you take this and that's the end of it.
Like there is a lot of nuance here.
But lower body generally requires higher reps and upper body generally requires lower reps.
Not to say that you should never do higher reps for upper.
But I think that the general concerns.
census is if you are
repping for if you're doing five or six reps
you're doing that for like for strength and not
hypertrophy right for strength uh and you got to lift really heavy for that what
i'm saying is if you want to if you're someone who's you know in the middle an
intermediate person be i think focusing on between eight to 12 even eight to
15 reps let's just say one and the last one or two
should be like almost a failure.
That would be what my guideline would be.
Yeah, that's a perfectly reasonable.
But I don't think that I actually disagree with you that I think that lower body should be
higher reps versus upper body that are lower reps.
I think you can interchange it.
Like sometimes I think sometimes I would do a lot of reps for pushups, for example,
or shoulder reps, whatever it is, right?
And then sometimes I'll just do heavier.
heavier, not to kill myself, but like heavier for 10 to 12 lower body. Because I think,
and then sometimes I'll change it up. I don't think one is necessarily. As I said, this is, it's not
gospel necessarily. Like I built when I was, I don't know, we mentioned that on this episode,
but when I was first starting, I was a teenager and I only did body weight. So I was doing incline pushups,
three sets of 35. And I built a lot of muscle in my chest. Right. Because you're, you're not.
Not normal, by the way.
I'm pretty normal.
Okay, just so you know, Leroyne was like a, almost like a, you were like a soccer player,
like a professional soccer player.
I did a little bit of everything.
I was quite good at everything.
Okay.
And he's like, you know, he has really good genes.
He has like a 20 pack without even working out.
Okay, never mind, okay?
So I'm saying, you like pumping out like 40 reps of a push up three times, majority of people is not,
that's not realistic.
Well, again, that was, it wasn't the first set I ever did. I built myself up to 35, but my point is, my body was transforming throughout that whole process. Now, look, if you want my personal opinion, yeah, that's why you're here. Generally, I'm going with the science and I'm also going with my experience for myself and for my, maybe thousands of thousands of clients that I've trained. Generally speaking, I wouldn't, if you want actual hypertrophy, like to see muscular size,
added, I generally wouldn't go as high as 30 reps. I would probably stick to somewhere in the
middle of that rep range. Okay, so then what do people gain if they're doing 30 reps of something?
Keep it simple. Just what do people get? What's the point of doing 30 reps of a lunge, in your opinion,
besides endurance and stamina? I do think you can build muscle on by increasing your reps from
15, 20, 25, up to 30, I probably would stop at 30. And again, if that's something that
cause for you, if as long as you are increasing your intensity, muscles can grow. Okay, so how are
you going to increase your intensity? Look, five more reps from 20 to 25 is still more intensity.
Okay, where are you going to go from there? Then you're going to do 50 reps? Again, a hundred
reps. Like, that's a lot of reps. If I'm giving a prescription to people, I would not go beneath
five reps and I would not go above 30 reps. And if you wanted to give yourself,
and easy, the quick and dirty on this, I would stick to somewhere in the middle. Me personally,
I'll tell you, I try to do 8 to 12 for upper body and 10 to 15 for lower body. That's how I generally
train myself. But there are times when I will go lower for lower body and higher for upper body.
So I'm saying, you do want to vary things sufficiently, but I would generally stick to the middle
of that rep range. I wouldn't go from either of those extremes. Does that make sense?
Makes enough sense, I think.
Yeah.
So 8 to 12 is a perfectly good rep range for basically every muscle group.
You're going to see some gains.
Okay.
I understand.
Today's episode is powered by AMP.
You know those days when you're just done.
I mean, the meetings, the kids, the to-do list, and you still want to move your body,
but the gym feels a million miles away?
That's exactly why I love my AMP.
Amp is a smart, AI-powered strength training device that sits right in your home.
It's super sleek, literally looks like you got it at the Apple Store, and it also counts your reps,
adjusts your weights for you, and you're always training under the perfect amount of tension.
So whether you've got 15 minutes or 45, AMP adapts in real time to make every workout simple,
effective, and completely personal. And the app is super cool too. It has hundreds of different workouts,
strength, Pilates, mobility, recovery, and it's so easy to use. It's literally been a game changer for me.
I don't have to plan my workouts or wonder what I'm going to do. I just turn on my amp and it takes care of
the rest. And as a mom and a business owner and a podcaster, that convenience means I stay consistent
and, you know, strength training, especially for women, is so key for my hormone balance, longevity,
and of course confidence.
So you can see why I'm obsessed.
Go to joinamp.com slash gen to learn more.
That's joinamp.com slash gen because strength should fit your life.
So what about classes like group fitness?
Do you think you can get really strong and muscular from doing group classes?
Oh yeah.
I have a group class that I teach called Bill.
on Monday and Wednesday evenings.
Really? And how does it work?
It's a, it's funnily enough, it's actually a circuit.
Okay.
So we'll have five exercises, total body.
So that way if somebody misses a class, it's not a big deal.
You're doing your upper push, you're doing your upper pull, you're doing core, you're doing
total body movement, and you're doing a lower body exercise.
So you've got those five exercises, you do three sets, 45 seconds, so they're timed each set
without getting into too much complexity of how the class works.
But long story short, you're doing total body,
and we just do it twice a week,
and the gains that people have made,
the people who come twice a week is really beyond my expectation.
And a lot of that is just the consistency
because there's a group and their cohort and they like each other,
they come like every...
Right, this is a community thing.
Yeah.
So, again, I think that there's a major thing with people
are now staying further away from, well, actually, I actually say, like, you know that bars are on
the down swing, right? People are not drinking as much and they're, they're actually using, like,
wellness clubs. Especially younger people. Younger people. Younger people. They don't drink.
Well, no, I'm saying, like, wellness clubs are on a huge uptick now. And, like, one of the number one
places people are meeting people, like relationships dating, is at running clubs. I mean,
people like, or like, that's what I'm saying, a group fitness environment. So like, again,
you're doing something, you're doing something that's good for you, which is like in your, like,
taking care of yourself. And it's also a very big social thing as well. I also think beyond that,
like if we're going to take a step, like deeper, I guess, a fitness is sexy. Like the truth of it is,
like we like to see people moving their bodies. Well, 100%. It's attractive. It gets something,
it triggers something in you that essentially turns you on. It's like it's chemical. We like that.
Going to a bar and drinking, yeah, you have to turn the lights down so people, you can't tell
what people look like. You have to drink so that you still can't tell what. Sexy, like fitness is
sexy because you see people honest and raw and who they are, how they move their body, how they push
themselves. You see a lot about someone. So I think you're getting a way better, essentially
kind of view of a person, of a human being, as a mate, as a potential mate. Well, I think it's
also like, you know, people who like sweat together, whatever together, you know, like, pheromones and
stuff. Ferramones, I think, I agree, I think it's super sexy, but more than that, I also think
it's, it's, it's, you're doing, you're doing, uh, an experience together. And that's kind of bonds people,
versus like drinking at a bar, right?
Like to me, it's like, okay.
Like, I'm glad to see this as like an uptick in terms of,
because for a while, I mean, younger people aren't even like dating as much, right?
So like the fact that like-
Yeah, they seem to be struggling in the dating.
They're struggling with the dating stuff.
So like the fact that like running clubs have become like such a big thing
in terms of for dating and for socializing and what was the other one?
Oh, I know.
I just came back from Miami.
And I, one thing that's...
Is that where the town is from, huh?
Well, yes.
Yeah, I could see something.
It's a glow.
What I was going to say is, you know what's massive in Miami that has not made it to the West Coast yet?
Something called Paddle or Padell.
I don't know how to say that.
Oh, yeah.
So you know how like pickleball has been like taken over the world and especially, well, everywhere?
Paddle is really big in Europe and it's become very big in Miami on the East Coast.
And they, it's, there is such a vibe and such a community around it. People exercise and like
they're obviously, it's great exercise. It's really a great vibe. What's the difference thing
pickleball and paddle? I'm going to tell you. It's also like they built like a whole community around it
where like people are like members at like multiple clubs. There's paddle clubs like, you know,
membership paddle clubs. And like you talk to people, you watch other people play. You play a game.
And to me, this is like, this is to me what it's going to like, I believe it's going to like take over pickleball pretty soon.
It hasn't yet made it, like I said, to the West Coast.
There's a few places here in L.A. that do it.
But it's not a vibe yet.
But it's so fun.
I feel like there's a little bit an element of more of an athletic element to it.
I don't know why you're doing it more in a cage, like what you have like walls or whatever you want to call it.
But to answer your question, how is it different than pickleball?
I don't know.
I'm not a big fan of pickleball.
I haven't played it very much.
You know, pickleball has like a kitchen, the whole thing.
I don't know.
But I really, like, that's what they call it.
The ball's different.
It's a plastic ball and pickle ball.
Paddle is, or Padell.
I don't, again, sorry.
I like Padale.
It's called a Paddle.
It's really big for, like, people from Argentina.
It's like Brazilian, like, is a very big.
That's why Miami.
And that's why Miami, it's become a massive thing.
You use a tennis ball.
So I think a lot of for,
former tennis players play it, but it's super fun.
Like, I guess the reason why I'm bringing it up is, like, to me, these are really great
ways to engage with people and socialize and build relationships in a setting that's
fun, interactive, experiential.
And to, and like, then you're like, you're then like with like-minded people who want to be
active doing something fun.
And so for anybody who doesn't know what, if you're living in a place where you should check
your local listing and see if you should go find a Padell place. It's so fun. It's so fun.
Yeah. I know they have one in Century City Mall. I know. So this is what I'm going to, so I literally
just got back from Miami. I'm going to go check it out because a bunch of people, I put it on my social
media. I was like, oh, I'm playing Padale. All these people were like, hey, you know what?
Like there is one in L.A. on top of, you know, Central City Mall. So I am going to look.
But like I said, part of the whole culture of Paddle is that you, I think there's like events around
it that people like hang out and they work.
Yeah.
Yeah, for sure.
You know, like, my brother's in real estate and I don't know if he does Pickle or Padell,
but one of the two or maybe both is, it's like a huge networking thing for them.
It's great for networking.
It's great for business.
It's great for socializing.
Like there's so many benefits to it.
Yeah.
I think this to me is.
where the future of fitness and social and business collides. Like, I think the, the collision here
is fitness and professional and personal meet. I agree. Even work has, you know,
taken a, has lost its social function because people are working from home or they're doing
hybrid models or, you know, they're not on work campuses. You know, these offices are closing down
the left, right. All this office space is for lease everywhere. Everywhere. Yeah.
People are closing down their offices and working from home and cutting the expenses.
So people need, we need a way to hang out with each other.
And I think play, especially physical play, is the best way for human beings to hang out with each other.
Totally.
I totally agree.
And so, yeah.
So maybe, you know, we should go play.
I'm down.
We should play together.
We should peddle.
I'm down.
I'm down.
And my girlfriend, Carrie, got me into it there in Miami.
And her and her fiance are like super into it.
and it was really fun.
And like I said, like I just think it was like it's a really,
I think it's like going to be pickleball, you know, 2.0.
Yeah.
And also, you know what's really interesting.
Do you know that pickleball has more injuries than like any other sport?
Yeah, actually it kind of makes sense now that I think about it.
You know, one of my best friends, I'm going to shout out to Mimi,
one of my best friends, she was like a big pickleball player.
and like she was playing pickleball.
This was like a couple years ago, maybe a year ago.
And she got like, she like fell backwards, hit her head and got like a major concussion.
And like supposedly like when she went to the ER, they're like, she's just quite clumsy.
I don't know how clumsy she is.
This happened to her lot.
I don't know.
I should ask her.
I feel like people like that.
Maybe.
Maybe.
I don't know.
You're right.
I don't know.
But she went to the ER and I remember she told me like she was not the first person there that day with a pickupball
accident.
She was like number six.
Uh-huh.
So, you know, that's really.
And another exercise or like another thing that is, has massive injuries, like you
would never think, mountain biking, mountain biking.
Yeah.
Yeah.
I mean, I had a motorcycle injury that really got me.
That's not the same.
No one should ever go on a motorcycle.
That's 100%.
Unless you've actually been on one before, in which case you've promised.
I know.
It's my first.
Have you ever ridden one?
No. Have you ever been on the back of one?
Yeah. Like when I was younger, younger and stupider.
I'm not telling anyone to do it, but
motorcycling is, let's be honest, dangerous.
It is probably the most fun you could possibly have.
Really? Okay, well, let's not promote.
I'm not promoting.
And, you know, make that a thing.
No one should go on a motorcycle ever.
I know a lot of people have died on a motorcycle.
You can die doing anything.
Look at me.
Do you know what I did to myself? Do you see this big bump on my head?
I guess, yeah.
Do you know what?
Okay, that's what I'm saying.
Anything can happen anywhere, okay?
I got this bump just to kind of give you like a, my trunk was opened and it was dark.
And like a complete dumbass person like I am, I just walked right into the corner of the trunk being, you know, being open.
I bumped my head so badly.
I like basically like passed out bleeding.
But I'm saying like you never know what can happen from minute to minute.
You should definitely not ride a motorcycle.
I don't plan to.
Yeah, definitely.
Intentionally, I should say.
Definitely do not.
Okay.
Well, anyway, so this is our little chit chat for today.
Thank you for coming on the show.
Thank you.
I look forward to being your Padel partner.
Yes, we're going to actually schedule that.
That's really a good idea.
Everyone try Padel.
Also, if you have not subscribed, guys, please subscribe.
It makes a big difference.
I want to hear from you.
I want to know what you want to,
what do you want me to talk about,
any topics you're just interested in,
any guests you'd want me to try to get for the show,

Thank you for having me.
And happy New Year to everybody.
Bye.
