Can you pat your head and rub your belly at the same time?  No?  Don’t worry, the condor can’t either.

Stand upright, feet together.  Raise arms laterally even with the shoulder.  As you circle them in a medium diameter forward, also raise up onto your toes.  Come back down as your circle completes.  If you can keep the tempo and not lose count, try to go twice as fast with your calf raises as your arm circles.  If you need another challenge, hold a five pound weight in each hand, or stand on the edge of a step and let your ankle hang off the edge as you do your calf raises.
