Before I can describe my training philosophy, I think it would be helpful to start by defining a few words commonly associated with Strength & Conditioning.

Exercise: Activity requiring physical effort.

Fitness: An organism's ability to survive in a particular environment.

Training: Undertaking a program of exercise and diet in pursuit of a goal.

Basically, Exercise can be any activity requiring physical effort, and our fitness is our ability to survive in a particular environment. When anything counts as an improvement, it's hard to pick a specific way to measure if we improved or not. With vague goals and random methods, we get marginal gains and inconsistent improvements.

Training, on the other hand, is comprised of many exercises, put together in a strategic way, with a specific target at the end of each segment. When exercises are planned in an organized, engaging, and progressive way, the process becomes something more than just exercising. Training is typically applied to sports performance enhancement, but maybe your "sport" is being able to play with your grandkids for more than 5 minutes before your back/hip/knee/etc. starts hurting you too much.

I'm committed to guiding you on a path to improved performance, whether you are a D I Athlete, a weekend Social Sport warrior, a grizzled Marathoner, or just a regular person looking to build a strength foundation. I'll finish with a quotation that I think summarizes my philosophy pretty well, just substitute 'martial arts' for 'strength training'. Or, realize, within yourself, that all methods of training are one method of training.

“The true science of martial arts means practicing them in such a way that they will be useful at any time, and to teach them in such a way that they will be useful in all things.”

I have not always been passionate about fitness. In fact, in High School I stuck mostly to bicep curls. That is, curling chocolate chip cookies into my mouth. I would occasionally try to exercise, and I might even keep it up for a while. Sooner or later though, boredom would set in and I would drop out of my exercise routine. After more than a few 'false starts', it finally clicked, and I discovered a true life passion. I’m in the best shape of my life these days, with much more on the horizon.

I am also an incurable nerd, so, even though I recently obtained my MS in Athletic Training, I'm continually monitoring the latest information and research.
