Don't let this move fool you — side skaters work the butt, hamstrings, thighs, and core. It also challenges your balance and agility and builds ankle strength. Pick up the pace on these, and in no time at all, you are sure to be out of breath!
If you find that you have a hard time balancing in this move, allow your back foot to touch the ground (as seen here), but challenge yourself by picking up the pace.
