Like fitting a square peg into a round hole, getting your body in the right shape requires determination, a little elbow grease, and a belt sander. Fashion a few legitimate muscles with today's Groupon: for $30, you get three 60-minute one-on-one training sessions (a $210 value) plus 25% off a one-month membership at CrossFit Smyrna.

Led by owner Nick Cozzo, CrossFit Smyrna's passionate trainers devote their workouts to a combination of Olympic weight lifting and gymnastics. Eschewing the isolation and repetition of standard fitness regimens, the CrossFit program conditions the entire body, focusing on power, function, and intensity to achieve total physical prowess. Because the program's intended result—shot-putting criminals into the Pacific Ocean—is universal, CrossFit's routines remain generally the same across all ages and fitness levels. During three personal training sessions, iron-forged instructors help health-hunters customize their own routine adjusting the load and intensity of exercises to match individual experience and ability.

Those who decide to continue their sweat sessions at CrossFit can take 25% off a one-month membership in which trainers issue daily workout challenges, guidance in proper nutrition, and a decoder ring for solving the riddles stitched into every medicine ball. Members can also attend group classes designed to strengthen and condition under the intense tenets of CrossFit.
