You have to mix up your moves to get cut abs, and this 10-minute workout does just that. After a short warmup, be prepared to go all out with a core-focused circuit filled with plank and roll-up variations that will leave your abs burning. For a fun twist on the basic plank, we use towels for gliders to make those variations more challenging. You can use gliders if you have them, or if you are on carpet, opt for paper plates. Press play, and get ready to feel the burn.
