Walking with ankle weights? Stop!
A well-rounded fitness program includes both aerobic exercise and strength training. But skip the ankle weights. Ankle weights may strain your ankle joint and leg muscles, which could increase your risk of injury. To get more out of your walking routine, simply pick up the pace. If you're in good shape, add short bursts of jogging into your regular brisk walks. If you're less fit, alternate leisurely walking with periods of faster walking.
