Early life and education of Jeff Cavaliere

Jeff has been fascinated with fitness since he was a little child. He used to watch action movies with muscular and robust protagonists, dreaming of becoming like them. Growing up, one of his favourite idols was Arnold Schwarzenegger. Jeff decided to follow in his footsteps and started going to the gym when he was in high school. He began lifting weights as a form of training for competitive sports and realized that he really enjoyed it.

After graduating from high school, Jeff applied to the University of Connecticut to achieve his higher education. He succeeded and obtained a Bachelor of Science in Physio-neurobiology/Premedicine but didn't plan on stopping there. He continued his studies until graduating with a master's degree in Physical Therapy. During his college years, Jeff became a fan of The New Your Mets, an infamous baseball team. He dreamed of meeting them and, luckily, helping them with their training. To get even closer to his goal, Jeff got certified as a Strength and Condition Specialist by NSCA.

Jeff Cavaliere with The New York Mets

As soon as he finished his education, Jeff started to work as a freelance physical therapist, helping all sorts of clients. One day he got lucky because The New York Mets player, Mark Johnson, came to his private practice as a customer. Mark was impressed by Jeff's good work and decided to recommend him to his teammates. Fortunately, there was just one job position opening, which was perfect for Jeff. Till that day, he worked his dream job as a head physical trainer of The New York Mets. In 2009, when Jeff worked for the Mets for three years, he started to question his future. He worked his dream job but started to get tired of the constant travelling. He began to feel like settling down, so he made the step and handed in his resignation.

Once he settled in, Jeff started to write down his experiences and tips. He published a few workout books while working on his own workout plan. Since he wanted to promote his training program and his business, Jeff started to post on social media under the name ATHLEAN-X. He used his Instagram to post pictures of his muscular body and YouTube to share his fitness advice. If it wasn't enough, Jeff had some other things working for him. As a former Physical therapist of a famous baseball team, he started to attract more famous clients, such as David Beckham and Rafael Nadal. The word spread, and soon after, Jeff became one of the most recognizable people in the fitness industry.

ATHLEAN-X YouTube channel

What differentiates Jeff from the rest of the fitness influencers is his education. He is trained to give useful advice, whether it refers to muscle growth or reducing pain. He used his knowledge to create a series called Best x Worst, which refers to different kinds of exercises. In each video, Jeff shows one of the most popular exercises for each muscle group and rates them based on effectivity. But since most of these exercises are doable only in the gym, Jeff created other series to please his non-gym buddies. Lots of people prefer working out at home, whether it is because of money or shyness. To teach them how to work out effectively at home, Jeff created the Home Workouts & Bodyweight Exercises series. There he explains how to effectively train in small spaces and how to replace gym equipment.

Since he worked with pro athletes, Jeff noticed that working out to gain muscle isn't the main problem. A lot of fitness enthusiasts suffer from back and neck pain and need to learn how to cope with it. This inspired Jeff to focus on this issue and inform people about the possibilities. His most popular video is How To Fix "Low Back" Pain (Instantly!), with over 34 million views. In other popular videos, Jeff covered wrong posture and other parts easily affected by pain. Overall, his channel helps people not only to build muscle and become stronger but do so in a healthy way.
