The gym is packed, and you’re sporting a shiny new pair of sneakers. It must be January! But 2013 will be different: You will get trim and toned for good. All you need is a plan that’s super-effective but doesn’t suck up a lot of your time—and this is it. Based on Jillian Michaels BODYSHRED (a new program at Crunch gyms nationwide), this 30-minute routine includes strength moves to sculpt sexy muscle, core challengers to whittle your middle, and heart-rate-revving plyometrics to blast calories. Team it with a healthy diet and Jillian’s motivational tips, and your resolution will become a reality before the gym crowd thins out.
How it works: Five times a week, warm up for 3 minutes by jogging in place or jumping rope. Then, do circuits 1 and 2 twice. Cool down with 3 minutes of low-intensity moves like arm circles, toe taps, and walking lunges.
You’ll need: A pair of 5- to 8-pound weights. (A mat is optional.)
