Increase the intensity of your workout with this heart-rate-boosting move.
-The Pendulum: Stand with your feet together. Now, lift your right leg to the side to hip height as you bend your left knee slightly and raise your right arm to the side. At the same time, swing your left arm across your body. By the next minute, you'll change sides as fast you can, sweeping your arms and lifting each leg. Keep going for a full 60 seconds. This move will boost the intensity of your workout and keep your heart rate up.
