About
After years of trying workout trends from popular fitness magazines, I learned what works and what doesn't work, the hard way. I enjoy helping my co-workers improve their physical health, so I studied to become a certified personal trainer. Let my experience help you meet your physical fitness goals. I will personalize your workouts to your wants. We will work hard, and you will enjoy the results.
