Matt Mackles

Certified Personal Trainer

Despite growing up with a passion for sports, it took me years to develop that same passion for fitness. Exercise and diet were always a struggle for me when I was younger and it wasn't until I cleaned up these aspects of my life that my performance, mood and ability improved dramatically.

I can empathize with the struggle of making big lifestyle changes. I realize there are no shortcuts. I understand there are going to be setbacks in and out of the gym. My strength is taking the guesswork out of fitness and nutrition so that my clients can spend their time and mental energy on the things that really matter to them.

I studied Exercise and Health Science at the University of Arizona and hold a PT certification from the National Academy of Sports Medicine. My scientific knowledge of the field along with my personal experience (and extremely high caffeine intake) makes me a great fit for anyone from a seasoned athlete to a first time exerciser.

Bob Bellon

Certified Personal Trainer

Bob has worked with over a thousand clients in his years as a personal trainer. He believes that all areas of a person's life improve when they exercise regularly and eat well. A former track and cross country runner, Bob began weight training in high school, and eventually realized that he could share his knowledge and his passion for fitness with others as well. He and his wife owned and operated their own fitness studio for six years, before selling it in 2015.

Now Bob works full time as a data analyst in the admissions office at Brandeis University. But his passion for training clients and helping people work toward their health and fitness goals brought him back to personal training at FT.

Bob lives in Arlington with his wife and two kids. When he's not working or spending time with his family, he enjoys reading, cooking, and learning new things.
