What we are ABOUT at EXSP

Explosive Sports Performance (EXSP) exists to help you enhance and improve the greatest machine known to man, “the human body”. It’s the one machine that you will use every day of your life. And in order to help keep it running efficiently and keep it healthy, we need to understand how to maintain this incredible gift.

EXSP helps our clients of all ages understand the importance of how the body works, how to improve it and how to transform it into the most dominate force on the planet. Let us teach you what you can do to help enhance your body each and every day.

EXSP was started in 2002 with the goal of helping our clients achieve athletic success. Our main focus has been helping athletes unleash their potential through speed, strength, power, mobility and stability training. Helping numerous athletes reach success at the college and professional level, EXSP expanded to its current location in 2004. The main motivation of training with EXSP is for our athletes (clients) to understand their own body and how to break through all obstacles they are presented with. 

With our expanded location, EXSP can service more clients/teams with an outside turf field, indoor turf running area and many other tools needed to help our clients unleash their potential. One of the major differences with EXSP over other facilities is that EXSP uses very few machines. We instead focus the training to mimic the environment experienced in your respective sport or activity. EXSP continues to help hundreds of athletes unleash their potential on and off the field which will always be a major point of emphasis for every program developed.

I can say that I would not have had the opportunity to play in the NFL without the help and unique training style of Dave at EXSP. The techniques in training were the biggest part because at my pro-day, there were guys that were more athleticly gifted but I still had better times. The specifics and breaking down parts of the drills helped me get better times than I thought I could get. The training on explosion and the hard work are essential to getting to where you want to be. I wasn’t used to this type of training so I saw results quickly. With the hard work you put in and the push from Dave you will see results. By putting in the work and listening to what Dave teaches, I believe that anyone can get done what they think they can. I will be using their training style for the rest of my career because it gets the job done.
