While it seems like ankle weights should help our leg muscles tone faster than without the weights, our legs aren’t designed to carry around heavy feet. There is more risk for injury of tendons and ligaments than toning leg muscles. If you want to focus on leg toning, your best option is some body weight workouts or exercises such as lunges with weights. People naturally lose muscle after 40, especially women after menopause. Because muscle burns more calories than fat, this can slow down your metabolism and make it harder to shake those stubborn pounds. Strength-training exercises -- lifting weights or doing body-weight exercises, like push-ups and squats -- at least twice a week can help you keep those muscles.
