From a seated, feet-forward position, place hands on ground slightly behind waist, fingertips facing forward. Straighten both legs, pressing heels and palms into the ground, and contract abs while lifting hips up, forming a straight line from head to toe. Keep gaze forward and shoulders pressed down; don’t lock your elbows. Lift your left leg straight up as high as you can (shown), then lower it without allowing your right hip to sag. Do 4 reps; repeat on opposite side.
