Exercise Philosophy
Physical change through exercise is a process known as adaptive response. Simply put, whether you are toning, building or reducing, your physiology will respond to meet the demands placed upon it. To maximize the adaptive response, training protocols must continue to challenge you, this is known as progressive overload.. At Ultimate Health we incorporate the latest weight training and resistance protocols including HITT and functional training (when appropriate) to effect recruitment of as many muscle groups as possible. See training for description.
Strength training is not enough, your workout program should include exercises that enhance stability, flexibility, aliment, balance, coordination and of course aerobic and anaerobic capacity. Training is one pillar of health, adequate sleep and proper nutrition are 2 others.
I have trained moms, dads, students, teachers, grooms, brides, firemen, policemen, marines, Navy SEALS, actors, professional athletes, and everyone has a fitness threshold. Elevating that threshold will bring you ultimate results. *
personal note
Enhancing and optimizing human health and capability has always been my passion. I became a personal trainer not because I fell back on it or because something else didn’t workout, but because I wanted to be a trainer, I was intrigued with the idea of helping others be healthier, fitter, more vital versions of themselves. It’s that passion that still drives me to continue to educate myself with the growing knowledge of the latest research in fitness training, strength building, dynamic movement, protein needs, recovery and aging. There is a vast and growing volume of new information in recent years due to a major uptick in new and better human randomized trials and I absorb it daily. These studies allow for the most effective true evidence based training and nutrition protocols. I follow the science not the noise and not the misinformation cluttering the internet.
As I have aged I find my focus has moved more toward health focused fitness. I still want to be strong, lean, fast, but I also want to extend my healthspan and that of others, to have great years to come and be self sustaining as long as possible.
