Get loose with these stretches recommended by David Reavy, founder of React Physical Therapy in Chicago. Do them three times a week, in order, before you exercise or on their own. "These moves work on the most common trouble areas for women," says Reavy. "You'll feel more balanced in the upper and lower body, create strength in the abs and get all your muscles working better." You'll need a foam roller and some lacrosse balls (don't sub in tennis balls; they aren't hard enough).

Hip Flexor Release

Tape two lacrosse balls together, lie on stomach and place balls just below right hip bone. Lean weight on balls, bend right knee at a 90-degree angle and swing right leg side to side. Do for 30 seconds. Repeat on other side.
