Start in side plank position with your leg closest to the ground up off the floor and your upper leg holding you up. Bring your bottom knee up towards your chest while you bring your free elbow to meet your knee right in front of your torso. Reach both arm and leg back into a slightly extended position. Repeat. Switch sides at the half way point.
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.
