Grace's arms and abs sculpt packs a focused burn into just 11 minutes, working your core, arms, and shoulders. You'll start standing with an arm series of circles, presses, and biceps, then take it to the mat for triceps, leg-and-core combos, and a deep oblique crunch series. It's a fully stackable workout—tack it onto the end of a longer class, do it after a walk or run, or use it on its own when you've got a few minutes to change your vibe. Grab light weights or go without.

Equipment: Light Hand Weights (2lb, optional)
