Jillian Michaels: Ripped in 30

Begin the program by learning proper form to get the best results. Complete three circuits of routines, which include three minutes of strength training, two minutes of cardio and one minute of abs.

Build on the basics with continued guidance about proper form. Week 2 heats up with plank jacks, squat thrusts and side lunges added to the mix.

You’re half way to getting ripped. Keep up your momentum with sledgehammers, standing stretch splits and bear crawls—the tough exercises you’ll need to reach your goal.

One week left until you're ripped! Leg swings, scissor hops, plank moguls—power through these intense exercises to finish the job.
