Side Plank with Hip Raise – Begin in side plank position. Keep your core tight. From this position thrust your hips up making an arch and back down. Repeat.
Woodchop – Stand with feet hip-width apart and core tight. Hold medicine ball in both hands. Lift the ball over our head toward the right. Next twist your body, bringing your arms down to your left side, as if chopping. Allow your knees to slightly bend in order to increase the ‘crunch’ in your abs. Repeat on other side.
