Start on your hands and knees on the floor. Tuck your toes underneath you and lift your knees slightly off of the floor. Switch the placement of your feet by criss-crossing them underneath you. It's best to add a hop to the movement so that the feet can move at the same time. Once you switch to the left quickly alternate to the right and repeat.
Do this exercise with the best exercise equipment. We recommend using a bluetooth chest strap heart rate monitor or a smartwatch for more training optimization & performance tracking.
