Beginning (my grandma on the left) – On the ground, step out one leg to the side so you are in a side lunge position then switch and touch the other leg out to the side.

Intermediate (my mom in the middle) – Using a low bench or step, put one leg on the bench while the other leg taps the ground, alternating sides.

Advanced (me on the right side) – Using a higher bench or stool, with one leg on the chair and the other leg on the ground, jump up and switch feet tapping the other foot on the ground. Keep alternating sides and repeating.
