Start in an upright plank position. Bring your right foot across to the outside of your left hand, then bring your left foot under your right knee and lift your left hand off of the floor. Retrace your steps and return back to an upright plank. Repeat on the opposite side, alternating between sides.
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.
