Step by step instructions
Start in a forearm plank position with elbows under shoulders and feet hip-width apart. Engage quads, glutes, and core the entire time to form a straight line from head to feet.
Lift left leg up to hip height, then kick out a few inches to the left. Come back to center and lower foot back to the ground. Repeat, this time lifting right leg and kicking to the right to complete 1 rep.
