After 10 years and 40 extra pounds acquired working in the computer science field, James J. Rivera spun his own weight loss and passion for fitness into a career. As an Independent trainer at CompleteBody FiDi (no membership required) and private gyms in luxury rentals, coops and condos across NYC, he strives to find the balance between exercise science, nutrition and empathy for the struggle we face during our fitness journeys. Established in 2012.

As a fitness late bloomer, I wasn't active & my metabolism finally caught up with me. I graduated from NYU with a degree in Computer Science & had a successful career in the field for over 10 years. However, it was never my passion. The longer I sat staring at a screen all day, the fatter I got.

At first, my workout was an outlet to make sure I made it through the day without abruptly quitting my job out of anger. As my body changed, I took interest in the science behind change - what makes program design effective? What nutrition & supplement choices will optimize results?

That's when I invested in education, certifications, & fitness related workshops. After applying those principles & seeing major results, people started asking me "what are you training for?"

"Life."

I was able to start over and do what I love. I moved up the ranks quickly to become an Elite trainer at the busiest Crunch in the country. Now I train independently at Complete Body and private gyms across NYC.
