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.
