Bow your legs out at around a 45-degree angle, arch your back slightly and put your arms out to your sides so that your elbows are parallel with your collar. Open your fists so that your fingers and thumb form a "C" when viewed straight-on.
Turn on the music, have a friend turn it on for you or just start singing.
Keeping your legs and arms in position, hobble back-and-forth and close and open your palms in beat with the music.
