Welcome to the smart woman's guide to becoming slim, strong, motivated, and focused in 12 short weeks.

We called in Jillian Michaels, the smartest, baddest, tough-love trainer out there — you've seen her on The Biggest Loser — to create your plan for success.

With this program, you could lose 5 to 8 pounds a month—that's 15 to 24 pounds by March. This isn't a lose-it-fast-then-gain-it-back scheme; this is the plan that works for life.
