In 2008, Ruben started Warrior Fitness Boot Camp which he owned and operated until 2016.

Mike was born and raised in Miami where his passion for fitness began at an early age. Growing up competing in Tae Kwon would attract Mike to hard work and discipline. After an injury sidelined him from playing College basketball, Mike began to fully dive into healing his mind and body through fitness. 

After beginning his coaching career 8 years ago, he has continued to educate and push himself to demand the best from his clients and group class athletes. He’s pursued education and experience in various sports/training methods. Mike strongly believes there isn’t “one” set way to train the human body and mind.
