Tone Up on the Treadmill

Tone Up on the Treadmill

Save time at the gym with this 10-minute cardio/sculpt session: Hop on a treadmill holding a three- to five-pound dumbbell in each hand, and set the speed to a brisk walk. Do a one-minute set each of shoulder presses, biceps curls, triceps extensions, side laterals, front laterals and standing triceps kickbacks one after another as you walk. I's an amazing upper-body challenge that also gets your heart pumping. Do this series two or three times each week. As you improve, work up to doing four-minute sets.
