Here's the link to the article: Plyometrics has exercisers jumping
I put my athletes that I work with at DC through a plyometric workout at least once a week, twice if they're no meet. It pushes them out of their comfort zone yet allows them to work on movements that will help them sprint and/or jump for each of their events. The results they've gotten having them added in: more explosion out of the blocks, quicker turnover in their strides, and more drive with their arms and legs. But you have to perform the movement correctly or there's a higher risk of injury. Start off with simple plyometrics and gradually build to more difficult ones. I don't know about any of you, but I wouldn't go out and run a marathon without training and working up to that distance.
Try jumping an invisible rope to start if your goal is box jumps, or squat onto a chair to work up to squat jumps or single leg squats. No one will think less of you starting easy. It just means that you took one step more than the person who chooses to do nothing.
Have a great workout! Get after it!
