Start in a plank position
Elbows to the ground and shoulder width apart
Butt down, legs straight, and back flat with toes dug into position
Extend right arm out to the side and rotate body towards the ceiling stretching the right arm to the rafters and balancing on the left (follow your arm with your eyes)
Rotate back to plank position but don’t rest that right arm to the ground…
Reach through under your left arm pit still balancing on that left arm (you should be in a one armed plank position)
Rotate that right arm back to the ceiling again in a full upward stretch and finally back to a double elbow plank position
Repeat moves with the left arm now…
Try this: 7 reps per arm for 7 sets
