Use Caution: Plyometrics

Speaking of jumping, plyometrics is a form of exercise (also called jump training), that works on your muscle power and explosiveness with a series of jumps. When done right, it makes for strong leg muscles. But it’s easy to do it wrong, especially if you’re going it alone. Landing badly can cause injuries, including problems in your joints. Before you start, talk to a trainer to see if it’s the right choice for you.
