This fast-paced move gets your heart rate up (to help blast body fat) and recruits your inner-thigh muscles to help you quickly switch directions.
How to do it: Stand with your feet together, arms by your sides. 'Shuffle' to your right by taking three quick steps to the side (right, left, right), and then lift your left knee up, swinging your right arm forward. Immediately reverse your shuffle (left, right, left) and land with your right knee up, left knee bent, swinging your right arm forward. Repeat 20 times in a row as fast as you can, alternating sides.
Form tip: This move is fast and should keep a steady rhythm—try counting '1, 2, 3' to help you stay quick and agile as you move from side to side.
