Are you ready?
B
I'm ready.
A
All right. Thank you for being here.
B
Thank you for having me.
A
You're very welcome. It's nice to have you. Okay, I got some quick questions for you. Ready?
B
Yeah.
A
Okay. Body weight exercises versus weights. What do you think is better?
B
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 press. You should be mastering push ups before you bench. Does that make sense?
A
Okay, yes. But in terms of, in terms of like building muscle, what is more effective?
B
I think you can. I think you can.
A
Again, like, could you build muscle with just body weight?
B
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 fast. And then when I started to lift weights because I had such a good foundation of movement, correct movement patterns, Stabilizer muscles. I know that's kind of bro. Science. I don't know exactly. You know what I mean?
A
Like nobody knows science.
B
Stabilizer muscles.
A
What are you talking about? Women talk about stabilizing science in terms.
B
Of like, you know, there's not a. There's not such a thing as a stabilizer muscle that people. No, I agree on what it is. But essentially the, that movement pattern, by working your body in a very balanced way that you get from calisthenics, from bodyweight exercises, it sets you up for weightlifting after. And I found that people who get good with bodyweight exercises first can put on muscle much faster when they do add weights.
A
Gotcha.
B
Does that make sense?
A
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.
B
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.
A
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.
B
And you can also push yourself at a really high level. So if you want to go super, super heavy so safely, machines actually really have their place. Because say you fail on a machine, what happens? The stack just drops on the stack.
A
Right, right, right.
B
Not on you. Exactly. So if you're trading by yourself things like Smith machines and cable machines and stuff like that. So I know you're 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. Leg press is just way easier.
A
Yes, right. Form wise, I think that's true. I also think, though, what do you think about this, actually? Because I, I know to get stronger and to get results, a lot of times it's about progressive overload. Right.
B
Yep.
A
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.
B
I think intensity is more important than weight. Weight is an aspect of intensity. But as long as the workout is sufficiently intense.
A
Well, what I, why I say this is because when I've worked out with trainers before, they're pushing me to go at such a, like, such 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 could do it. I'm like, I really actually cannot do it. Like, my glutes are not firing. I have an injury over here.
B
Like, 100% true.
A
And the reason why I'm bringing this up is I think it's really important to really be discerning 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. 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, lift super, super, super heavy. No, you gotta 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 the, that's not also the answer.
B
It's great advice. Don't kill yourself.
A
Well, don't kill.
B
Generally speaking. Generally speaking.
A
Well, I think. Yeah, well, just generally speaking. Well, I was gonna say, what is your opinion on this, like lifting super heavy?
B
I agree with you 100%. I mean, the research says anywhere between five and 30 reps is good for hypertension. Five and 30?
A
No, I heard between eight and 12.
B
Right. So that's, that's the traditional one. But 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.
A
I'd like to see that research because I have not seen that.
B
I think it's by Andy Galpin, so you can check that out.
A
But again, he says, he says that because if you're doing 30 reps, that's more endurance than anything else.
B
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 and 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 found that varying things smartly, right? Like in, in a periodized and structured way is the best way for me to train because it keeps things fresh and exciting for me.
A
Well, I think what you're talking about is more muscle confusion. So 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.
B
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 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 body.
A
But I think that the general consensus 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. I. 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 8 to 12, even 8 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 then.
B
Okay, that's perfectly reasonable.
A
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 push ups, for example, or shoulder, 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.
B
I said this, 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 push ups three sets of 35. And I built a lot of muscle in my chest.
A
Right. Because you're, you're not normal, by the way.
B
I'm pretty normal.
A
Okay. Just so you know, Leroy was like a. Almost like a. You were like a soccer player. Like a professional soccer player.
B
I did a little bit of everything. I was quite good at everything.
A
Okay. And he's like, you know, he has really good genes. He has like a 20 pack with. Without even working out. Okay, never mind. Okay, so I'm saying you, you like pumping out like 40 reps of a, of a, of a, of a push up three times. Majority of people is not. That's not realistic.
B
Well, again, that was, that was. It wasn't. When I first. It wasn't the first set I ever did. I built myself up to 35. But my point is I was. My body was transforming throughout that whole process. Now look, if you want my personal opinion.
A
Yes, that's why you're here.
B
Generally, I'm going with the science and I'm also going with with my experience, for myself and for my maybe thousands of thousands of clients that I've trained, generally speaking, I, I wouldn't. If you want actual hypertrophy, like to see muscular size being added. I generally wouldn't go as far high, as high as 30 reps. I would probably stick to somewhere in the middle of that rep range.
A
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, 30 reps of a lunge, in your opinion? Besides endurance and stamina?
B
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 calls for you, if as long as you are increasing your intensity, muscles can grow.
A
Okay, so how are you going to increase your intensity if you're doing 30 reps?
B
5 more reps from 20 to 25 is still no.
A
I know, but then, okay, where to go from there? Then you're going to do 50 reps again, 100 reps, like that's a lot.
B
If I'm giving a prescription, okay, I would not go beneath 5 reps and I would not go above 30 reps. And if you wanted to give yourself an 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?
A
Makes enough sense, I think.
B
Okay, so 8 to 12 is a perfectly good rep range for basically every muscle group. You're going to see some gains.
A
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 45amp 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. Like, I don't have to plan my workouts or wonder what I'm going to do. I, 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.comjen to learn more. That's joinamp.com Jen because strength should fit your life. So what about classes like group fitness? Do you think you can get. Do you can get really strong and muscular from doing group classes?
B
Oh, yeah. I have a, I have a group class that I teach called Build on Monday and Wednesday evenings.
A
Really? And how does it work?
B
It's a, it's funnily enough, it's a, it's actually a circuit.
A
Okay.
B
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 pole, 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, because there's a group and they're cohort and they like each other. They look, they come like every.
A
Right. This is a community thing.
B
Yeah.
A
So again, I, I, you know, I think that there's a major thing with people are now staying further away from. Well, actually, I should say for like, you know, that bars are on the downswing. Yeah, right. People are not drinking as much and they're, they're actually using like wellness clubs.
B
Especially younger people, like, stuff they don't drink. It's like.
A
Well, no, I'm saying like they don't drink. Wellness clubs are on a huge uptick now and like one of the number one places people are meeting people like like relationships. Dating is running clubs.
B
Yeah.
A
I mean, people like. Or, like, that's what I think. A group fitness environment. So, like, again, you're. You're doing something extra. You're doing something that's good for you, which is, like, in your. In, like, taking care of yourself. And it's also a very big social thing as well.
B
I also think beyond that, like, if we're going to take a step, like, deeper, I guess fitness is sexy. Like, the truth of it is, is, like, we like to see people moving their bodies.
A
Well, 100%.
B
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 can't tell what people look like. You have to drink so that you still can't tell it. 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.
A
Well, I think it's also like, you know, people who, like, sweat together, whatever together, you know, like pheromones and pheromones. I think. I agree. I think it's super sexy. But more than that, I also think it's like you're. It's. It's. You're. You're doing. You're doing 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, a uptick in terms of. Because for a while, I mean, younger people aren't even, like, dating as much. Right. So, like, fact.
B
Yeah. They seem to be struggling in the dating.
A
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.
B
Is that where the town is from? Huh?
A
Well, yes.
B
Yeah. But see, something.
A
What I was going to say is, you know, it's massive in Miami that has not made it to the west coast yet. Something called paddle or padel. I don't know how to say it.
B
Oh, yeah.
A
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.
B
What's the difference between pickleball and paddle?
A
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 LA 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, in a, 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, 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. It's. That's what they call it. The ball is different. It's a plastic ball. And pickleball paddle is. Or Padel. I don't. Sorry.
B
I like Padel. Let's call it Padel.
A
It's really big for like people from Argentina. It's like Brazilian. Like it's a very big. That's why. And that's why Miami and that's why Miami. It's become a massive thing that you use a tennis ball. So I think a lot of 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 like 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 Padel place. It's so fun. It's so fun.
B
Yeah.
A
Yeah.
B
Well, I know they have one in Century City Mall.
A
I know.
B
So this is.
A
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 at. I'm playing Padel. All these people were like, hey, you know what? Like, there is one in LA on top of, you know, Center 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.
B
Yeah, for sure. You know, my brother's in real estate, and I don't know if he does Pickle or Padel, but one of the two, or maybe both is. It's like a huge networking thing for them.
A
It's great for networking, it's great for business. It's great for socializing. Like, there's so many benefits to it.
B
Yeah.
A
I think this, to me, is where the future of fitness and social and business collides. Like, I think the collision here is fitness and. And. And professional and personal meet.
B
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. Left, right. All this office space is Felice. Everywhere.
A
Everywhere.
B
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.
A
Totally. I totally agree. And so, yeah, so maybe, you know, we should go play. We should play together. We should.
B
Padel.
A
We should. Padel.
B
I'm down.
A
I know. 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. Like I said, like, I just think it was like. It's a. It's a really. I think it's, like, going to be pickleball, you know, 2.0. 2.0. 2.0. Yeah. You know, and also, you know what's really interesting? Do you know that pickleball has more injuries than, like, any other sport now?
B
Actually, it kind of makes sense now that I think about it.
A
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.
B
I don't happen to her a lot.
A
I don't know. I should ask.
B
I feel like people like that.
A
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 an accident. She was like, number six. Six.
B
Uhhuh.
A
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.
B
Yeah. I mean, I had a motorcycle injury that really got me.
A
That's not. Yeah, that's not the same. No one should ever go on a. A motorcycle that's 100.
B
Unless. Unless you've actually been on one before, in which case you.
A
I know, my friend.
B
Have you ever ridden one?
A
No.
B
Have you ever been on the back of one?
A
Yeah, like when I was younger. Younger and stupid.
B
I'm not telling anyone to do it, but motorcycling is, let's be honest, dangerous. It is the. Probably the most fun you could possibly have, really.
A
Okay, well, let's not. Let's. Let's not promote and. And, you know, make that a thing. No one should go on a motorcycle ever. I know a lot of people 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?
B
I guess.
A
Okay. Do you know what. Okay, like, that's what I'm saying. Anything can happen anywhere. Okay. The. I. I got this bump just to kind of give you like a. My trunk was opened and it was dark and like a. 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. Like, you never know what can happen from minute to minute.
B
You. You should definitely not ride a motorcycle.
A
I don't plan to.
B
Yeah, definitely intentionally. I should definitely do not.
A
Okay, well, anyway, so this is our little chit chat for today. Thank you for coming on the show.
B
Thank you. I look forward to being your padel partner.
A
Yes. We're gonna. We're gonna 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? Please. It should be an open dialogue here. So with that being said, thank you for being here, thank you for having me, and Happy New Year to everybody. Bye.
