Walking is Britain's No. 1 form of exercise - and with good reason. It's easy, cheap, and can be done anywhere. Now, Prevention Magazine takes fun, low-impact walking to the next level with a new 8-week program that will help readers lose 3 times more weight - and keep it off. Designed by certified fitness trainer Michele Stanten, the program jump-starts weight loss with core and lower body strength exercises as well as special walking routines, including interval walks, which research shows burn calories twice as fast as regular walking. Women who tried the program for 8 weeks: lost up to 221/2 pounds and 12 inches; lowered their blood pressure and blood glucose levels; had less back and joint pain; and, improved their posture, balance, flexibility, and boosted their energy. Paired with a delicious, well-balanced meal plan and easy strength-training exercises, Walk Off Weight also helps readers pick out the perfect walking trainers and gives them technique tips to increase their speed and avoid soreness or injury.
