Personal Trainers & Fitness Bootcamp

CEO and Founder Dontrell Britton grew up in Adams Morgan as a native Washingtonian. He has always been passionate about sports, competition, and fitness. As a young adult, Dontrell was involved in some criminal activity which led him to prison. While serving a 5-year sentence, Dontrell was not only thoroughly rehabilitated but also discovered new, and innovative workouts that dramatically transformed his physique. It wasn't long before "Trell The Trainer" was born! He began teaching these same techniques that helped hundreds of inmates to get ripped. Released in 2015 on good behavior, Trell The Trainer continued to pursue his passion for training launching his company in the summer of 2016. 

Since then "Trell The Trainer" has helped a 1,000+ clients to get in shape and hires returning citizens as trainers to teach his signature class "23/1'. Trell The Trainer has been featured on ABC's Channel 8 and a list of other local publications. His objective is to motivate and inspire his peers and community to embrace fitness and wellness as a way of life.

Chelaea Smith on Twenty3N1

- Trell encourages you to dig deep and work towards your personal potential. He pushes you beyond what you think is your limit, and helps you to strive to be a better you. I believe he truly wants his clients "to fall in love with the process." If you are looking for someone to push you to a whole new level of fitness and good health then he's the man you need to connect with. I have seen my body change in the short months I have been training and can only imagine and looking forward to more growth and results.

- Dontrell talks about falling in love with "The Process." Before, I didn't get it.

He's a great motivator and leads by example.
That is falling in love with the process. It's simply getting at it and most importantly, keeping after it. Dontrell legit has changed my mind in as many ways as he's transformed the body I live in. Can't say enough about how good this dude is. The game done changed.
