For this full-body strength class, you'll go all in with 45 seconds of each exercise and a 15-second recovery afterward, followed by a 30-second burner. It kicks off with a warm-up to prep your body before diving into the two circuits, which are repeated twice. You’ll get a full-body workout by powering through moves like biceps curls, jumping lunges, weighted bicycles, and ending with a spicy ab burner.

Equipment: 5lb-15lb Dumbbells
