Working with PSP has changed my life!

"After a knee injury caused me to have surgery almost 2 years ago, I started working with PSP to help get back into shape. Since then, I have learned volumes about general fitness and clean eating. I am in the best shape of my life and feel great. I love the fact that, every time I go to PSP, I have a completely different workout, tailored to my specific needs and fitness goals. In addition, if my knee is bothering me again, or another event creates an injury (as when I fell down the stairs and hurt my shoulder), the coaches at PSP are ready with stretching and/or exercise suggestions to help the situation. They truly care about helping me to become the strongest and healthiest I can be. I recently competed in my first triathlon and finished with the best time I could have imagined, feeling strong and recovering easily."* Ann A. Winnetka, IL|Read More Testimonials
