HOW: Begin in a tall plank position with your elbows straight straight down from your shoulders and legs straight out from your hips with your toes pushing into the ground. From here, lift one arm up overhead and maintain that position for the prescribed amount of time.
FEEL: You should feel your shoulder and core muscles working.
COMPENSATION: Keep your shoulders, hips, and ankles in a straight line. Don’t twist when in the three point position, maintain your plank. Try not to lean over to your down arm.
