Cardio: Sideways Stair Run
Time: 30 seconds
Start at the bottom of the stairs with your right side of the body closest to the stairs. Leading with your right foot, run up the stairs sideways. (Pretend your feet are chasing each other. Right foot goes first but as the left foot starts to approach the first step, the right foot should already be lifting to move up to the second step.) When you get to the top, walk down the stairs normally. Repeat.
