Imagine you are watching the RADIO CITY MUSIC HALL ROCKETTES. They are known worldwide for their synchronized high kicks while standing in a single file line across the stage from left to right. List the muscles which must work to:

B. Now which muscles must come into play in order to extend the right leg on the thigh (to get the high kick)?

C. Don't forget to list the opposition muscles that must relax in each part of the above maneuvers.

D. And finally, don't forget to list the muscles in the left leg, thigh, and hip and what they are doing so the Rockette doesn't fall down and go boom.
