Kayaker

Start: Grab a body bar or broomstick with both hands and lie back on a stability ball. Movement: Extend your arms straight above your chest, brace your abs, and crunch up to lift your shoulders off the ball. Hold this position for all the reps. Keeping your arms straight, pull the bar to the left, allowing your torso to rotate to the left. Bring the bar back across the middle and pull to the right, rotating your torso to the right. That's one rep. Do 15.
