From age 30 at 17% body fat to almost 50 at 8% body fat!

This was my best deadlift in competition, a 475 lb. lift at only 158 lb. bodyweight...and it was good enough for a medal!


Upon graduating the National Personal Training Institute in 2008, Jason DeAngelis started his own personal training business. After five years of successfully building up a client base he launched the All In Fitness brand in Belmar, NJ in 2013. In 2020 he relocated across town into a larger, brand new facility. During the Covid-19 pandemic, when gyms were temporarily closed, he started another unrelated business. In 2023 after running the facility for a decade and training over 1000 clients, he closed his doors to focus on more life balance while transitioning towards online coaching.

In addition to almost 20 years of industry experience, Jason has a diploma in nutrition and is a published fitness writer including working as an online contributor to Men's Health magazine. He's a former three sport high school varsity athlete, and college football prospect. Before becoming a trainer he completed five marathons in just two years time and successfully competed and placed in several powerlifting events well into his 40's.

His true passion is working with athletes while helping average men and women change their lives to become healthier through discipline and consistency. His approach with all his clients focuses on the importance of managing stress, eating whole foods, strength training regularly and getting quality sleep.
