Calories burned: About 200 per 20-minute session*

Celeb poster child: Cameron Diaz

Super-short (usually 20 minutes or less) and intense, these workouts may have you climbing ropes and sprinting one day, then doing handstand push-ups and lifting weights the next. Many of the hardest routines are named after women (Angie, Diane). We love this woman power!
