Tommy Day

Instructor

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.

Ryan Venezia

Instructor

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.

Coyle Coaching

“I have been a successful business owner and entrepreneur since 1998 and since then I have worked very hard to grow my company and my businesses. A year ago, Laura was recommended to me by a client and close friend after I told my friend that I was beginning a business franchise. My friend instantly said to me you absolutely have to hire Laura Coyle as your business coach. She’s tough and will guide you in a powerful and positive direction. She couldn’t have been more right.

Coach Laura has kept me on the road to success and, through her kind and professional guidance, has allowed me to be more productive than I have ever been. She keeps me accountable to my goals and keeps my negative saboteur demons at bay. I would not be as productive or as positive about my business progress without her. Coach Laura is the bomb!"
