Fire up your triceps and biceps in just 30 minutes! Begin with a warm-up during this strength class, then grab a pair of dumbbells to power through exercises like bicep curls, push-ups, overhead presses, and more. You'll do each of the 4 exercises for 45 seconds, followed by a 30-second burner. Push yourself during each exercise; you won't repeat any of them! Finish off with a strong 3-minute burner at the end.

Equipment: 10lb Dumbells
