Your tendons are under a lot of tension when you exercise, especially when you do explosive activities like sprinting and jumping. If these thick bands of tissue, which connect muscles to bones, are too stiff, they won't be able to properly handle all of the force from those activities.

Ideally, your tendons should be very elastic, meaning they stretch like a brand-new rubber band. The more they stretch, the stronger they rebound. Just like a rubber band, tendons are more likely to tear when they become too stiff. Ballistic stretches help prepare your tendons for tough workouts.

Ballistic stretches are quick movements that bring your muscle into a stretch and then are quickly released. It's not ideal if you want to focus on making a specific muscle more flexible, because the stretches don't last long enough. However, ballistic stretching help make your tendons more elastic, according to a 2007 study in the British Journal of Sports Medicine.
Use ballistic stretches wisely because you can get hurt. Don't push the stretch too far, and don't move too quickly. As long as you get a stretch and quick rebound you're helping your tendons.

Wall Calf Stretch
Although this isn't a ballistic stretch, it gently targets the large Achilles tendon.
How to: Stand in front of a wall and put both hands on it. Stagger one foot back and the other foot forward. The toes of your back foot should line up with the heel of your front foot. Keep your back foot completely flat on the ground and bend your knee forward toward the wall. Slowly get closer to the wall for 30 seconds, then switch sides.
