“Underground fitness has had a huge impact on my performance in my chosen sport of American football. Since i started, my conditioning has gone through the roof – my body is now more accustomed to pushing on at a high level even when it feels like I hit a wall. More importantly, I’ve developed explosive power that I never thought I’d have. Progressing in the different aspects of Underround training has transferred into stronger movements on the field. I can hit harder and maintain my balance while being hit. I’ve been going to the gym for years, thinking I was doing good but always wondering why I was never progressing. thanks to smart programming, good coaching and efficient, hard training, I’ve come on in leaps and bounds since I started. I doubt I’ll ever go back to a “normal” gym again.”
