Star Glide
A hip-hop glide exercise where you slide across the floor like you're ice skating. The standing foot stays in forced arch with all the weight on it, while the other foot slides on a diagonal, about a centimeter off the ground. Less contact means less resistance.
Switch weight, slide the other way, and travel through all four walls. Once the slide and the switch are clear, let them happen at the same time so the glides join into one smooth line.
