Boot camps are a quick way to get in shape for upcoming marathons or adrenaline-pumping prison escapes. Jump the fence with today's Groupon: for $39, you get 10 boot-camp classes (a $113 value) at the BodyWorx location on Richmond Street. Classes are available Thursdays 5:30 p.m.– 6:30 p.m. and Saturdays 9:30 a.m. –10:30 a.m.

BodyWorx shapes sagging silhouettes through individualized training plans and a variety of supplemental classes. During each boot-camp session, the motivational drill sergeants at BodyWorx use students’ instinctual distrust of routine to their advantage. They keep muscles guessing with new and challenging moves during each session, so you never fall into a boring, ineffective routine, like regular teeth brushing. Classes focus on core strength training and weight loss, with exercises specifically tailored for each body's shape and affinity for pleather. Fitness fanatics and exercise amateurs ages 16 and older are all welcome.
