SIDE REACHES PERKY CHEST WHITTLED WAIST

This lateral movement isolates the hard-to-tone obliques to help carve out an hourglass silhouette, says Calabrese. Plus, the reach engages the pectorals to lift and firm the chest.

TO DO: Take a wide step out to the right and bend your knee into a lunge. Place your right hand on your right knee; reach your left arm up and over your head, then return to start. Do 10 reps, then switch sides.
