Basic move: Total-Arm Toner
Sitting on a step or low, sturdy table with your legs together and knees bent, place your hands on the front edge, knuckles facing outward. Straighten your arms to lift your rear off the table or step. Bend your elbows to lower your rear toward the floor, being careful to stay as close as possible to seat. Slowly straighten your arms; repeat 8 to 10 times.
