 “Long before I ever touched a weight I grew up a huge fan of pro wrestling and action movies.”


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


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

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’.

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.
