There is no messing around in this 30-minute workout . . . except for the short dance break to shake things up before the final circuit. Barry's Bootcamp trainer Allie Cohen keeps things moving by mixing strength training with cardio moves in this eight-exercise circuit workout. No muscle goes unworked in this fast-paced boot camp, and if you're new to fitness, don't worry. We offer beginner modifications for each of the moves. Grab a pair of medium-weight dumbbells, between five and 10 pounds (we like using eight pounders), press play, and get ready to warm up and work.
