This concept is just killer. I am always looking for new, fun and unique ways to work out. Unfortunately, bobbing on an elliptical machine for 45 minutes just does not do it for me. I get bored and restless at about the 6 minute mark. Cue Derby Lite! It’s a workout based on roller derby, only without the aggressive hits. Each 2-hour workout includes off-skates conditioning, dynamic warm-ups, on-skates skills and drills, upper body strength exercises and cool-down stretching (aka; not boring). Unfortunately, Derby Lite is not offered in Miami (wah!), but you can submit a form requesting that your city be added. I did, and you should too!
