Keep the rhythm no matter who's dancing next to you with this simple move.
Start standing with your feet together, arms bent at chest level with your right hand clasping your left wrist. Step your right foot out to the side a little wider than hip width and lean into it while you release your wrist and pull your elbows behind you at shoulder height, keeping them bent about 90 degrees.
Step your right foot back into your left as you bring your your arms in and clasp your left wrist with your right hand again. Now, step your left foot out to the side and lean into it while you raise your arms overhead, right hand still clasping the wrist. Continue alternating sides.
