Wiley Wadsworth

I am a Bay Area local and a student at UC Berkeley. I have played soccer for 18 years, and currently play on the Cal Women's Club team. I also played club water polo and dabbled in numerous other sports. I love working out.

Most of my training experience comes from Air Force ROTC, in which I am a fourth-year cadet. For a semester I led the advanced workout group, before moving on to take over the entire fitness program, which I led for another semester.

My favorite types of workouts combine cardio with strength. Don't expect a lot of rest! I love pushing people to and past the limit, and showing them they are capable of much more than they think.

Lance Moore

Why Personal Training: I am a personal trainer because I love the art of boxing and love teaching the art to others. I like the release that hitting the bag and boxing in general give you. I got into boxing to increase my fitness. I was in top physical shape but when I went to box against an opponent, I couldn't touch him and didn't feel in shape. This experience sparked something in me. The more I went, the more I liked it and wanted to compete in it. I want everyone I teach to get a really solid workout while having fun. Working out without working out. I have been teaching boxing for 8 years, I've been training on my own for over 20 years, and have an amateur record of 11 wins and 1 loss.

Charla completed numerous 5k's, 10k's and marathons. Since, she has retired from running as well as from the fire department due to back/hip issues and picked up indoor biking.

One the best feelings for her is watching students of all ages and fitness levels come to her classes, groove to the music and reap the benefits of keeping their bodies in motion.
