Jesse Anderson

With over 25 years of fitness and martial arts experience, Jesse Anderson has taken training and fitness to a whole new level. The fitness industry has been slowly changing. With the boredom of running on a treadmill, or going to an overcrowded gym and not seeing any results, it’s time for a change. “I have enjoyed training my whole life. I would spend most of my time hitting the heavy bag, sparring, running, doing pushup, sit-ups, bur-pees, and then go to the gym to lift weights. I realized that there had to be a better way. 11 Even though big clubs are still very much a huge attraction for those that are looking to get fit. The truth is that the novelty and motivation wears off after a couple of months. “I started training people the way I enjoy training myself using boxing, kickboxing, and/or MMA conditioning drills along with a specific weight regimes. And viola! A fun way to train, hit hard, get your frustrations out, sweat, and see noticeable results.
