Chugs
A traveling chug exercise that works the inner thighs and core as you move front and back. Start in a deep second position with the knees over the toes, back straight.
The whole body moves together in one motion and stays at the same level. Think of the inner thighs wrapping around and pressing back. Hands clap from a fist to an open palm, then the arms cross to the shoulders with two hip hits.
