This exercise is far more challenging than it appears. Once you get past the challenge of balancing the ball on 1 hand and 1 shin, (opposite hand and shin, btw), you'll begin to feel the burn within the first 8 reps!
Without alternating, lower and lift your right arm and left leg for 10-20 reps, then repeat with the left arm and right leg. For your first go at these, I'd recommend 10 reps per set for 3-4 sets. As you get stronger and are able to keep your hips tucked forward longer, (no arch in the lower back), then increase to 15 or even 20 reps for 2-3 sets.
Stay tuned - the next few weeks the Hard Core move of the week will be progressions of this exercise to intensify your workout and continuously develop your core strength.
