Chapter 1: Who is Jeff Cavaliere and what is his mission in fitness?
Jeff Cavalier is the physical therapist and strength coach trusted by the NFL, MLB, WWE, and even Sylvester Stallone. He's built a global reputation for science-based training that delivers. What do people want?
When we poll our followers, I found that for men, they want their six-pack abs, getting bigger arms, develop their chest. And for women, they want to have better legs and well-developed backsides. So we'll get into those exercises. But the biggest problem most people have is the struggle to get started.
Chapter 2: What motivates people to start and stick with fitness?
I get emotional, but it's sad when people don't ever find that drive and motivation, because the detrimental effects that prolonged sitting can have on your body, they call it the new smoking. Like, if I take away your health, you're done. So finding the drive to get yourself on track with pursuing optimal health is everything.
So if I was one of those people struggling to get the ball rolling, where would you start with me? I would start with... And I'm not done yet. Lower belly fat. How do I get rid of that?
calories in calories out but surely you say that there are five key exercises to maximize your longevity and quality of life can you show me these workouts sure and then why did you bring the skeleton with you with the bow tie this is raymond and i use him to show one of the most fascinating areas of training that has yet to be uncovered
I find it incredibly fascinating that when we look at the back end of Spotify and Apple and our audio channels, the majority of people that watch this podcast haven't yet hit the follow button or the subscribe button, wherever you're listening to this. I would like to make a deal with you.
If you could do me a huge favor and hit that subscribe button, I will work tirelessly from now until forever to make the show better and better and better and better. I can't tell you how much it helps when you hit that subscribe button. The show gets bigger, which means we can expand the production, bring in all the guests you want to see and continue to do in this thing we love.
If you could do me that small favor and hit the follow button, wherever you're listening to this, that would mean the world to me. That is the only favor I will ever ask you. Thank you so much for your time. You're very much known as the king and the OG of online fitness training, advice, support.
In terms of the mission that you're on in particular and how your perspective differs from other people out there in the market, what is it that you think makes your perspective different, unique, and more important potentially than a lot of the perspectives out there as it relates to how to build up our muscles, how to have a strong, healthy body, and how to prolong our health span?
Everybody, for the most part, that's out there trying to put information out they should have a level, there's a level of respect I have for everyone doing that, because they're all trying to help people get better or improve themselves.
I think where I was really heavily focused was on a more comprehensive, more multifaceted way to do that, because my background wasn't just in, let's say, strength training or and aesthetic appeal of training, but also as a physical therapist and having a physical therapy background, I understood the importance of not sacrificing the body in the process of trying to aesthetically improve the body.

Chapter 3: How does nutrition impact fat loss and muscle definition?
And that's a cool thing because wrestling, though some people may not like the storyboarding of wrestling, athletically, they're some of the most gifted athletes in the world. I mean the travel schedule, the amount of days that they wrestle every week, the rigors that they put their body through. Whatever you want to say, the outcome might be determined, but the bumps and bruises are not fake.
And they also have to have that aesthetic appeal too. So it's this combination of athletic and aesthetic that always appealed to me.
When I look at someone like you and I see these bulging muscles and I see how lean you are, it's very easy to fall into the trap of thinking, well, you were just born with extreme motivation and that's why you are the way that you are.
Well, I think motivation is extremely overrated, right? Because motivation isn't what produces the results. It might get you to the show and get you to actually show up at the gym and initiate the work, but only discipline keeps you there. And being disciplined is the number one asset somebody can have. Now, discipline comes with finding success.
So at an early age, if you can, or an early training age, if you can experience some success early, you do become motivated, again, self-motivated to continue on down that path. So My genetics were never great. My mom was five foot tall. My dad's five foot nine, five foot eight, 160 pounds, not a lot of muscle. I definitely have surpassed my dad in muscle.
But I didn't come from this genetically gifted pool of cavaliers. There's no way. But I did have this desire to do something in terms of training and taking my body as far as I could. But I really found the discipline through... the fact that I liked it. And I found that this was feeding me in other ways. It was making me feel fulfilled. So it was easier for me to stick to it.
You must deal with so many people that are struggling that come to you and they say, listen, I've got these big goals. I'm overweight. I don't feel good. I've got diabetes here, cardiovascular problem here, inflammation here. And they say to you that they want to change. You know, you can see it in their face. They're desperate, but they don't change for whatever reason.
We live in an age now where You have access to the internet. You have so much access to information. Use it in whatever way you can to get started on your journey because the earlier you start, the better. But it is quite sad when people don't ever find that spark in trying to play catch up. There's no lie to it. It's going to be harder as you get older.
Starting or initiating a training program in your 40s and 50s, though way better than not starting one, is much more difficult than if you had started in your teens and 20s.

Chapter 4: What are common misconceptions about abdominal fat and abs training?
know to develop that habit to maintain that habit it's very difficult to initiate that the older that you get but i do think that it's possible so my best advice to people who have that struggle to get started is to figure out ways that you can eliminate thinking right because the longer you think the more likely you are to not be able to do it you know the thing that stops most people
There's that saying, the start is what stops most people, right? But at the same token, it's not the obstacle that's in your way. It's the fact that the path of least resistance is more inviting. So you wind up saying, well, I don't know. I could just sit on the couch and watch this. I'm not going to go to the gym.
And believe me, there's even nights now for me where I'll be with one of my sons and we'll be in his room putting him to bed. I might fall asleep in there and wake up and it's late at night. I don't even think. I let my dogs out. I go right outside. I walk.
Sometimes I'm literally half asleep as I'm walking, but I know if I can get to the gym, get in there, turn on the music, and kind of put the lights on and do one warm-up set, I'll be good. And if I even sat down for a second— I might find that path of least resistance to be a lot more inviting and that couch to be a lot more comfortable.
And then once it becomes something that you enjoy, because for the most part, I think you probably enjoy it now, right? The process. It becomes a lot easier to make that automatic step. But there's still going to be days, you know, maybe a long day of shooting, you know, and you're going to be like, maybe not today.
But if you stop the negotiation with yourself and you just go and make that first action, that's all it usually takes to get you through the door and you realize what you were set out to do.
When you think about all the many millions of people that have watched your videos, I mean, it's actually billions of people that have watched your videos and consumed your content. you must hear a lot of different types of spark. When I say spark, I mean the moment in someone's life where something happened and it stuck, it finally stuck. What are the kind of things that you hear?
Oh man, they're life-changing. It's part of the why that keeps me going, hearing some of these stories. I had a live event recently, a few years ago, first one that we ever had. So I was a rookie. I didn't know how it was going to go. But part of that event was a competition that we ran. So anyway, we had a guy who was in his late 50s, first one to do the competition. So he drew number one.
So he goes, and the first thing we had was a 300-yard shuttle, which is just a 50-yard distance they had to run to the cone and back. That's 100 yards back and forth again and back and forth again. It was extremely hot that day. It was like 95 degrees because of course I ran the event in July and it was like, okay, this is not going to work out so well.

Chapter 5: What are the risks and realities of steroid and growth hormone use?
And the friction of the sled on the ground was not really something that was accounted for. It made it even more difficult. Well, again, he's got that bloodied up knee. He's pushing it. He gets it to the end, struggling. And now he has to pick up at the end a 100-pound kettlebell and walk it back. He goes down there.
He grabs the kettlebell after a long, multiple attempt to get the sled down there. And I finally run down there and I said, his name is Craig. I said, Craig, dude, you don't have to do this. You're good. You're good. It's okay. And he's like, no. He says, I'm going to do it. And I start walking and he's crossing the legs over each other. It looks like he's going to go down again.
I put my arm around him. I said, man, listen, you don't have to do this. He says, no. I get goosebumps. He goes, Jeff, I have to do this. He goes, I was diagnosed with MS four years ago and I can't feel my feet. I got to do this. It's that kind of drive and motivation. And you never know because you don't know what they're dealing with.
Chapter 6: How should one train for longevity and maintain functional fitness?
I get emotional, but it's like that's the kind of stuff that gets me going. We had another guy who competed at our event. And he was doing the push-up portion of the competition. It's the second year. And he was doing his push-ups. He wasn't going all the way down. So got down to like, I don't know, two, three inches away from his chest. So I go over to him.
I'm like, hey, dude, just still a little bit lower. Get your chest down. He says, I can't because I have a port in my chest and I have stage four cancer and I can't get all the way down because of the port. He wound up dying two months after the competition. So when you realize that people do this for reasons that you don't like, it's not just to go to the gym to get a six pack.
It's going there for reasons we'll never know. And I think that those kinds of moments are more than touching to me, as you can tell. But they show the power of will. And that is something that we'll never be able to quantify. Yeah.
Within that is what I was thinking about how that guy who wouldn't put that 100-pound kettlebell down, for him it was actually about a story he wanted to tell to himself. It's something that he wanted to do for... Reasons that are much more about one's identity and one's self-story, as we call it.
And on that particular point, it's one of the things that I often think about with fitness and working out is if I can be the guy that grabs the keys that day when I don't feel like it, then how that permeates through the rest of my life and how I show up in the rest of my life when there's things I don't want to do.
And how that then shapes me over time into somebody who is able to have the difficult conversation, is able to confront the thing, I think is like really understated. I actually was reading this, I think Andrew Huberman told me this. He said that neuroscience has found a part of the brain which is associated with doing hard things.
Yes, I saw that.
And I think he said basically that that part of the brain, and I'll put this up on the screen, grows the more hard things that you do. So you basically build the muscle of being able to do hard things.
And the minute I learned that, I went, oh, this makes a lot of sense because the more I was able to make the workout stick and the health and fitness stick, and now my diet is like, as we sit here now, is extremely disciplined. I've changed as a person in other areas of my life. I've got more organized with my possessions and my...

Chapter 7: What are the five key exercises to improve longevity and quality of life?
If you start to like the thing that you actually didn't like in the beginning, then it no longer challenges that area of the brain. That area of the brain starts to shrink again. Oh, really? So it has to kind of, which is cool because it means that you need to continue to seek challenge.
I was thinking a lot about this over Christmas and New Year's. I sat down with one of my best friends and said to him, I said, what exercise and what thing do you dislike the most? And we basically made a list of them. And then we started doing those things.
That's cool.
It was actually running and it was leg day. And squatting. It also made me, because when I asked him why he didn't do those things, the list of reasons he gave were things like, my legs aren't, insert excuse, my brain, insert excuse. And we both came to realize together that that was just a bunch of bullshit that we had like made our identities and it was now limiting us.
Are there things like that in your life that you just...
Oh gosh, yes. Conditioning, running. I try to address those things and do them knowing that I should do more of them, but there's always more to do.
One of the things you must have figured out from all the content you've produced across all these channels is really like the essence of what people want. Because you'll see from the views and the engagement and these things, you'll build this sort of mental pattern of, okay, people are really interested in this.
So if you had to summarize for me the essence of what you think people are looking for, and when I say the essence, I mean like the why, why, why, why, why, the very bottom of that. What are those things? Oh, I think, I think,
Insecurity is definitely a factor. I think a feeling of wanting to be accepted is part of that. I think a feeling of wanting to be more capable Because I think a lot of men carry insecurities of how capable they are. If the moment arose that they needed to, let's say, protect their family or do something that was physically needed to be done, how capable would you actually be?

Chapter 8: Why is thoracic spine rotation important and how do you maintain it?
I heard this quote many years ago, it says, change happens when the pain of staying the same becomes greater than the pain of making a change. And I was thinking, if you were my trainer, and I was one of those stubborn people who were struggling to get the ball rolling, where would you start with me? Like, what would you do if I was super stubborn? I tried for three years, I'd never made it stick.
But clearly there was health consequences playing out in my body. Where would you start with me to get me going?
Oh, the conversation. I would start with always with the conversation. I think it is important to see if you can understand the why for somebody. Because if you ask this question, this is an interesting exercise to do, but if you ask the question of like, why do you want to get in shape? You might say, I'm too fat right now.
And I would say to you, what would it mean to you to not be as fat as you think you are? Well, it would be better because I'd have a six pack. what would be important about having a six pack? Well, I would like how I looked in the mirror more. Why would it be important for you to like who you're looking at in the mirror?
Because I don't feel like I'm enough right now because I'm letting myself down because I know that I'm not doing the things I need to. Why is it important to not let yourself down? So when you start to ask the question, keep digging, you find the why very quickly. And a lot of times it comes from pain from childhood. It comes from pain of letting others down.
It comes from a feeling of inadequacy that you developed either because it was... drilled into you from your parents or others, or because you just never lacked the self-confidence to actually feel better about yourself.
I always say that most people who are lifelong gym goers, they all have some level of pain in their life that caused them to seek this out because it's the one thing they can control. It's the one area where it's like, I don't have to listen to anybody. I have to do what I have to do for myself, and I'm in control of my body.

Chapter 9: What is 'nerd neck' and how can posture affect fitness gains?
And I think that a lot of times people, or it's an escape, where you benefit from the endorphins that are released through exercise, and it's your escape for doing something to make yourself feel better. But a lot of times people get into fitness as an escape from some of that pain. So if I had...
You would come to me in the very beginning, I would have started with that conversation and tried to find out why is it that you can't stick with this? You've tried and you stopped. And I think that people need to understand that and finding the why to get yourself on track with pursuing optimal health is everything.
What about the very top then? Like how does it manifest like the title of the video or the thing?
I mean, the top is abs, biceps, chest, and low back pain. I mean, people actually come to me for one of two things. Again, I think it's having the two hats of physical therapist and strength and conditioning coach. I think people come to me to fix something or to improve the look of something.
So we have lots and lots and lots of views, obviously, based around fixing issues, low back pain, postural issues, knee pain, shoulder pain, and how it disrupts their ability to carry on in life or through their fitness pursuits. Then there's the other side of it where people, of course, they want their six pack abs and then they want their arms and they want their chest.
And I highlight those because the fact is that is where people are most interested because it's, It's the beach muscles, but it's a fact of life. People want to improve those areas. What I try to do when I bring people in through that track is to also make them aware that, okay, this is cool. You want your abs. That's good. But obviously, this can require a healthier eating plan.
So I know I can have a much broader impact on their overall health and life if I can get them to eat much healthier than they are right now. So I always feel that you can come in for whatever your top level interests might be, but my mission and goal is to make sure that you understand there's more to it than that.
I've kind of broken everything you've said into three sections, which is people want to look good. They want to perform in whatever that might be. And they also want to be able to do it for a long time. They want to live long. So if we start with looking good as a top line category, what are the things that you think are the subcategories of looking good? The amount of fat.
that someone carries, so how lean they are, the aesthetic development of their muscles, what their bodies are shaped like, because you could lose weight, but as you've described before, skinny fat isn't really an attractive look. So I think they want to develop their muscles in specific ways.

Chapter 10: How does grip strength relate to overall health and longevity?
What is the difference you see between what men say they want versus what women say they want? What do men come to you and say that they want to?
As a trainer of athletes, it's sacrilegious to me, but they really discuss anything in the lower body. They're not talking about, I just want really big legs or I want to have strong, developed glutes. I mean, it's just not really high on the list. So pretty much everything is going to focus on from the waist up in terms of the aesthetic desire. bigger neck for men. For women, it's the opposite.
For women, they focus first and foremost below the waist. They want to have better legs. They want to have stronger legs. They want to have well-developed backsides. There's probably a cultural importance upon that. Men are being judged aesthetically on their upper bodies more than women are. And women are being judged more aesthetically on their lower body.
So we're feeding into those desires, especially, you know, one scroll through Instagram and you're just reinforcing everything I just talked about. In that category as well of looking good, nutrition? Most importantly, the level of body fat that you carry is going to be impacted by nutrition.
So let's start with fat and lean. If I want to be lean like you and I want to have low body fat, where does one begin?
What happened with me and what I always advise people to do is start just by looking at globally from 30,000 foot view, what do you know you're doing not well right now? Are you drinking excessively? Do you end every night with a pint of ice cream? You know that you're doing some things wrong. So you make one pass at the obvious stuff.
And you just do it for a couple weeks, you know, and you see how you progress. And what will normally happen is usually those are the most offending, the biggest offenders when it comes to nutrition, that you will notice some quick weight loss when you stop it.
What do you think are some of the offenders that we don't realize are offenders? I've had so many in my life, even like ketchup.

Chapter 11: What are Jeff’s views on supplements like creatine and protein powders?
Chapter 12: How does sleep timing and quality affect fitness and recovery?
