Hip Twister Plank
Move Targets: Core and obliques
Step 1: Begin in forearm plank position with shoulders directly over elbows. Your body should be in a straight, diagonal line from your head to your heels.
Step 2: Keeping your abs in tight and your shoulders above your elbows, rotate your torso as you drop your left hip to the ground.
Step 3: In a controlled motion, rotate your torso to the opposite side, dropping your right hip to the floor. That is one rep. Repeat for the allotted time.
Step 4: In between rotations, stop in the middle to get control of your balance if necessary.
Modification (beginner): Perform this move on your knees. Make certain to keep body in straight, diagonal line!
