I know there are at least a few bloggers out there who have tried Body for Life. It's a 12-week diet and fitness plan--fairly stringent--that's designed to help you lose weight and build muscle. (Although I tend to think it's mostly a "cutting" plan rather than a muscle-building plan.)
The basic tenants are this:
1. 5-6 mini meals per day, each of which contain one "portion" of protein and one "portion" of carbs
2. A "portion" is a serving approximately the size of your palm or fist
3. Veggies--like spinach, lettuce and broccoli--can be added to every meal
4. Workouts are either cardio (20 minute high intensity interval sessions) or weights (a half pyramid with a compound pump set)
5. Workouts are rotated each day (day of cardio, day of weights, day of cardio, etc.) six days a week
6. Day 7 is a "free" and "rest" day; no exercise, and you can eat anything you want
Follow the plan and you'll get visible results in 12 weeks.
Personally, I have always believed that Body for Life is a solid plan. It teaches portion control, regular eating habits and regular exercise. It balances cardio and strength training. And it teaches us to indulge--just a little bit--every once in a while.
Hubby and I are thinking about starting up this program again on Monday. I'm looking forward to it.
