Lunge and twist:
Step out with your left foot and assume a lunge position. While facing forward, bring your arms out, shoulder level, parallel to the ground, hands clasped. Twist at the trunk to the right side until your shoulders are completely turned. Imagine your arms have moved from 12 o'clock to 3 o'clock. Remain in the lunge position, but bring arms back to starting point. Finish one set, then switch to the other side.
