Best Total-Body: Kettlebell Kickboxing Scorcher Series

Pricey, yes, but this four-DVD set has 10 different workouts that combine kettlebell training with martial arts movements to burn major calories (500 in 25 minutes!) and target muscles you didn’t even know you had. Bonus: You’ll dig creator Dasha Libin’s athlete- like energy.
