Based on the wildly popular New York City classes of the same name (SMASH star Megan Hilty is a big fan), Kettlebell Kickboxing: Scorcher Series ($59.95 for the 4-DVD set; kettlebellkickboxing.com) combines the power and strength of martial arts and kettlebell training for a dynamic, explosive workout that burns up to 1,000 calories in one hour. Created by certified trainer and martial arts expert Dasha Libin Anderson, this intense workout program uses a kettlebell (or dumbbell) to help slim, define, and sculpt your entire body.
What to expect: The 4-DVD set includes a total of 10 complete workouts, ranging from 35 to 60 minutes in length, as well as a clean eating booklet. For best results, Anderson recommends doing the program three days a week.
You'll need: A kettlebell or dumbbell (5 to 20 pounds, depending on your fitness level).
