Tommy Day

As a lifelong athlete (NCAA football, track and field, gymnastics) and as a trainer since 1991 (SFPA certified), I have had the opportunity to experience many different training techniques. For best results, my standard workout usually hovered around two to three hours (weights, cardio, stretch, shower), four times a week. If I did any less I felt I would be short-changing myself. Boy, was I wrong. I get the same results doing SlowBurn™ as I did before, and I don't have to organize my life around my workout! I love what SlowBurn™ does for my body and I love seeing what it does for our clients.

Throughout his experience as an exercise instructor, Ryan has learned:

1. Exercise, specifically strength training, is a human requirement
2. Efficiency and safety matter the most
3. There is a lot of health and exercise misinformation

Ryan’s focus is on coaching clients on injury prevention, longevity, and overall health. SlowBurn personal training addresses the importance of these things in the same way that Ryan does. Ryan is happy to be able to apply his strengths and passions at SlowBurn to improve the health and well-being of all of our clients.
