I’ve followed Khoi for a very long time on Instagram before finally biting the bullet and started training with him. Over and over he’s shown that his nutrition coaching program works. I was fortunate enough to live locally to him to have him coach me in nutrition but also personal train me. Khoi is one of the most prolific personal trainers in Orange County. If you want results that are long lasting and quickly, Khoi is the personal trainer to work with in Orange County.


Dropped by one Saturday morning to try out this facility’s power vinyasa class. The instructor Tanya was freaking awesome! She’s real in tune with how her yogis feel and adjusts her class to best suit them. I prefer Fit Body Life Training Center’s small, intimate, and personal yoga classes over the big chain yoga classes where I’m just another face in a room of 50+ people. Tanya focuses on each of her yogis to make sure we are doing each pose correctly.
