Jeff Cavaliere

 

Jeff Cavaliere is a fitness guru, social media star, personal trainer, and previous head physical therapist of the New York Mets ( professional baseball team).

He became fascinated with bodybuilding after seeing Arnold Schwarzenegger and action movie stars as a child. As a result, he chose to study physioneurobiology and physical therapy at college – in order to pursue a career in the fitness industry.

Since then, Jeff has become one of the most recognizable online fitness sensations – known for the training system he developed after leaving his position with the New York Mets.

This is his story:

Biography

Early Years

Born and raised in Connecticut (USA), Jeff Cavaliere discovered his passion for fitness at a very early age; he idolized professional wrestlers, action stars and bodybuilders, such as Arnold Schwarzenegger,  who all had shredded physiques.

After becoming fascinated with these muscular celebrities, Jeff began desiring a similar frame as he grew older. However, it wasn’t until high school that he started lifting weights in the gym.

Start of Fitness Journey

As he entered high school, Jeff was introduced to weight-lifting during competitive sports classes; he realized that training in the gym was his key to achieving his dream physique – which would also help him improve at his hobbies such as baseball and soccer.

As a result, Jeff worked hard to gain lean muscle mass, becoming both bigger and stronger in order to play sports at the highest level.

“After one summer of consistent workouts, I not only started to see abs, but was finding it easier to get my job done on the field.” – Jeff Cavaliere

College

After graduating from school, Jeff enrolled at the University of Connecticut to study Physioneurobiology – going on to also complete a masters degree in Physical Therapy.

During this period, Jeff became a huge fan of The New York Mets – watching every game as an avid supporter. For this reason, his dream was to work in the industry as a physical therapist after he graduated.

With his sights set on this goal, Jeff studied hard to earn his masters degree, and make his dream a reality.

“I grew up an avid Mets fan. I lived and breathed the team and watched every inning of every game all the way through college.” – Jeff Cavaliere

Physical Therapist

Almost 5 years after he started studying at the University of Connecticut, Jeff graduated with both a BA degree in physioneurobiology, and a masters degree in Physical Therapy.

Having gained the necessary qualifications, Jeff didn’t waste any time; he opened a private practise in his hometown. However, he never took his eye off his goal – to earn a job in the baseball industry.

New York Mets

During his time working independently as a physical therapist, Jeff was able to work with elite sportsmen – such as Mark Johnson (a New York Mets athlete). After impressing the baseball star with his work, Mark informed Jeff of an opening at the club, after the head physical therapist had transferred to another baseball club.

With a high recommendation from Mark Johnson, Jeff successfully earned the position of head PT at his dream club, the New York Mets – fulfilling his ambition of working in the baseball industry at the age of 31, in 2006.

“I essentially went from my private practice in CT/NY to the big leagues in a matter of 2 months.  

It was a dream come true for me and an opportunity that I will cherish and remember fondly forever. It changed my life.” – Jeff Cavaliere

Entrepreneur

After 3 years serving as the head physical therapist and assistant strength coach for the New York Mets, Jeff made a huge decision; the immense travelling that came with his job had taken its toll, and he began to reconsider his position after moving around 14 cities in only 1 days.

Jeff became tired of living out of his suitcase, and his new marriage had given him a desire to spend more time at home. As a result, in 2009, at the age of 34, Jeff handed in his resignation from the baseball club.

However, this only made him more determined to start a new chapter of his life; almost immediately, Jeff authored numerous workout books, and developed a training system that would become 1 of the most popular online fitness guides.

“In the winter prior to my 2008 season I got married and bought a house, and finally the pull of “home” and getting a chance to spend a summer day with my family became stronger than my desire to stay in the game.” – Jeff Cavaliere

Social Media Star and Fitness Guru

Over the next decade, Jeff worked hard to advertise his workout guides – getting the chance to work with elite athletes, such as David Wright, David Beckham, Rafael Nadal, and Terrell Owens.

As a result, Jeff became recognized as a leading figure in the fitness industry, known under his nickname ‘AthLEAN-X’.

“While I always go in with a plan, my ability to change things on the fly to react to the effort I’m getting on a given day.”

Nutrition

In terms of his diet, Jeff has always known the importance of nutrition when aiming to sculpt a shredded physique. He enjoys eating 6 smaller meals spread throughout the day – this ensures that his metabolism is running high and helps him stay lean all-year-round.

Jeff plans his meals around lean proteins, fruit & vegetables, and complex carbs – although he cuts carbs out of his diet later in the day. He incorporates protein shakes to help him reach his macros for the day.

Diet Plan

Breakfast – 8:30am 

  • Pumpkin oatmeal
  • Scrambled eggs & salsa
  • Skimmed Milk
  • Kiwi slices

Snack – 11:00am

  • Protein shake with a banana and strawberries

  • Cajun grilled chicken wrap with grilled vegetables, sun dried tomatoes and hot sauce
  • Greek yoghurt
  • Sparkling water

Snack – 4:00pm 

  • Black bean, vegetables and onion soup

Dinner – 7:00pm 

  • Sesami tuna steak

Post Workout Snack – 10:00pm

“I idolized guys like Arnold, Stallone, Ravishing Rick Rude, and The Hulkster, I found myself wondering what it would actually take to look like them.”

Idols and Influences

As a child, Jeff idolized bodybuilders and action movie stars, such as Arnold Schwarzenegger; these were the people who inspired Jeff to sculpt a shredded physique.

However, since he became an online personal trainer and social media star, he motivation comes from seeeing his clients work towards – and reach – their fitness goals.

What We Can Learn From Jeff Cavaliere

One thing we can learn from Jeff, is to set our goals high and do whatever it takes to reach them; being a lifelong New York Mets fan, Jeff set himself the aim of working for the club after graduating from college – a target he reached after gaining experience at his private physical therapy clinic.

Jeff has taught us to always keep improving ourselves – he earned his dream job at the New York Mets, but after marrying his wife and starting a family, he needed a new profession that allowed him to spend more time at his home. He left his job, but he through hard work and dedication, he’s since become one of the leading fitness guru’s in the industry.

    Jeff, I can’t even begin to tell you how much help you have been to me. Over the last eight years, I have gone through an incredible physical, and metaphysical, transformation. YOU were always there for the biggest part of it, and in the end, allowed me to win a rather large Physical Transformation Challenge! Since then, because of the incredible desire for fitness that has been reignited in me, I returned to school to receive me MSPT (it’s a step down, education wise, but it accompanies the Ph.D. in Kinesiology, that I already possess) and I have also received my PICP Certification. Proof that God truly has a sense of humor…after going through my renewal, I am now dealing with a failing heart. The real stinger is… my cardiologists tells me that had I not gone through my transformation, and lost over 250 pounds, there is no question that I would not be here, today. Ergo, I literally owe you my life! How do you thank someone for something like that? Now, to top everything off, one of my past trainers; and now good friend, tells me that he has met you. AND, I’ve also been told that one of my people actually wrote your office and heard back, with them saying your team wants to hear my entire story. I’m in the process of writing an up to date bio, so as soon as I get all the data together, I plan to answer your team member and send you “The Rest of the Story!” Ha!!!

    Thanks for ALL that you do, Jeff. Congratulations on your, MUCH DESERVED, accolades. Blessings to You, Jesse, all of the Athlean X team and fellow Athlean-xer’s out there.

    Stay ‘Healthy,’ My Friends!

Nw I understand all ur videos properly. I’m a certified trainer n I’m planning to open my own gym. I know it’s impossible to meet Jeff but one day sir, I will meet u n fullfill my wish. U really mean a lot to m coz u earned my dedicated respect. Luv u Jeff always n 4 ever

    I’ve been lifting weights to fit since my college years. Through the years of training I acquired injuries like sprained wrist, low back pain, and popped AC joint. By watching Jeff’s video I learned a lot and changed my approach to training. Now, I can train without the pain. Thank you Jeff.

    I watch your videos often . I enjoy watching all your videos more so the ones on back injuries. I lower lumber is at its weakest but I don’t let it stop me from staying positive . Since watching your videos they have helped me do work out better and what stretches are good to do and what to avoid. I find that my lower body is a lot more work to lean out due to my back, as a like to be more shredded in my legs and glutes more aswel as the rest of me. This has saved me a lot in Chiropractor cost.
    Your are a great inspiration. Amazing person .

    I sure he is not on steroids… but people have been accusing him of being on TRT!…Is that true???…Ive never seen any other fitness youtuber claim him to be a steroid user…. that probably speaks volumes…but im just curious.

    Jeff – I am 60 and I am following your videos – its amazing what is happening to my body ! Thanks so much ! I have to ask you a question – you seem to like Cajun products and your last name is French – how French are you ? I’m a Cajun boy in Lafayette, Louisiana. We have a world class gym here called Red LeRille’s – my life revolves around that gym right now ! You should come down and visit ! LOL !

    Hi Jeff, you should do some videos on youtube specifically on muscle nutrition for men in their 40s and 50s….its easy to lift and get stronger up until your 30s but once u hit 40 things slow down a lot, most men in their 40s cannot look like u at all no matter how hard they try….a lot has to do with supplements so u better start talking about that too, I know it can be “legally” risky to give advice on supplements but surely you can say what you take? Unless u wanna keep it a big secret. I think without the right mix of supplements its impossible to have the strength at your age to lift properly and be so fit.

    I do like your videos a lot, very informative….hope to keep seeing u with fitness advice for the next 40 years (at least).

    Totally agree with you all! Thanks Jeff! I spent Years trying to become the image of A. Schwarzenegger. I just got ripped off with bulking supplements and ended up fat! Jeff, you shown me the way! Il never be huge but I’m well on my way to being the best version of myself that I can be and that’s all because of the decency of one Mr. Jeff cavaliere and his will to share the knowledge (for free) that he worked so hard to learn himself!

    Hi! Thank you, Jeff!
    A year ago, I was not able to walk. I couldn’t stand straight. I was leaning away from the pain! At that moment, I was searching for a good treatment and guess what! I found your youtube channel, the “How to Fix a Bulging Disc (NO SURGERY!)”
    I watched it! I was also 22 like Jessie! You explained really well, what the hell is happening inside our bodies when we have a herniated disc.
    Then I start to do the plan that you had given to Jessie. It was the first exercise that really helped me!
    After that, I started to follow your youtube channel and watch your videos daily.
    And then, guess what?!
    After one year, I went and got an MRI and the doctor said: “Your disc is OK. You don’t need any surgery!” Thank God!
    Your advice was really helpful and my disc has been centralized again!
    As you told, just like 98 percents of people my disc is now in its correct position. I really appreciate you. In fact, I love you, Jeff. Your attitude was also helpful in this process.
    Thank You!

    Hi, I’m on a Keto diet and it doesn’t seem to be working for me. I can’t seem to eat enough fat and it causes my body not to go into ketosis, which means my body turns the protein into carbohydrates and I cannot loose the weight that I hoped to loose. Any suggestions?

    Jeff isn’t French, Kevin Rees. He’s Italian. “Cavaliere” is Italian for “knight.” The French spelling would be “Chevalier.” And as his bio says, he was born and raised in Connecticut, although I agree that I can hear a definite Southern twang when he speaks, which makes no sense since he IS from Connecticut. That’s probably what’s making you think that he’s a Louisiana Cajun.

    Anurag Kumar,

    If you’re 19, you may be toward the end of your growth. I’m not sure than anyone knows a workout routine for height, either.

    However, get your proper nutrients. Naturally, you’ll need to ensure sufficient calcium for bone growth. But most, most, most importantly: Get your sleep!!

    That’s the hardest thing for young people to be consistent with, yet it’s the most important for growth.

    So, get out there, work hard, eat well, and sleep! Your height is largely determined by your genetics, as far as is known, but doing those things should maximize your potential for further growth.

    Jeff,

    I’m not sure if this is the correct venue to pose a question for you. Hopefully you get this. I’m 50 years old, 5”8 tall, 175 pounds. I’ve worked out my whole life and about a year ago I was diagnosed with a slap tear of my right shoulder labrum. 30 years ago I had a slight tear in the supraspinatus tendon, so I’m think the instability of the shoulder had been there for quite some time).

    I got opinions from three docs and was planning to have surgery, and then got diagnosed with a right hip labrum tear (former long distance runner) and had the hip surgery first.

    My thinking was that while the shoulder was healing from surgery I would at least be able to ride the bike and get some cardio in by having the hip done first.

    The doctor that performed my surgery did not do what we discussed (reattach labrum) and just shaved down part of the labrum. My hip is no better now than it was before the surgery and I can’t help but wonder if the shoulder surgery could yield the same result.

    my question:

    While watching one of your videos last night, you mentioned that you had a labrum slap tear. Can you tell me if you had surgery or steer me in the right direction as to what you think would be best for FULL recovery & FULL ROM.

    Working out has always been the biggest mental release I have, and I’ve been struggling for over a year working around the injury and thinking surgery might be best .

    Thanks so much for taking the time to read this!

    The stats can’t be correct unless he is on physique altering drugs. If he is short and 5’8″ and looks this ripped, then he is probably no more than 160-165 lbs (probably even 154 lbs) before he will look soft and have higher body fat percentage even with more muscle.
    I have a three degrees, exercise physiologist, licensed dietitian, worked as a trainer for 6 years, work in nutrition counseling. He is evasive online about his stats, so my opinion is he is 155-160 max if natural and this site is full of shit when it comes to real body stats. Being lean just means having less muscle if natural. I’ve been an athlete my whole life and know the same if not more training principles than he does because of my background and experience. Physical therapy is a rehab professional, fyi. I do not see a doctorate or license either.
