The Biggest Winner – Maximise Back in Action DVD

A challenging program created to reshape the "back" of your body: back, biceps, buttocks and hamstrings. Jillian Michaels, the boot-camp-style trainer from TV's "The Biggest Loser," is tough, demanding and relentless ("do not stop, I know you can do this!").

Like all her workouts, the format is straightforward – a fast-paced series of individual exercises (10-30 reps per set, each set never more than one-minute long). For example, "morning glories, jump lunges, plank twists, double crunches, side lunges."
