Tuck Jumps – Stand with feet a little bit apart and knees only slightly bent. Squat down and then explode up and jump as high as you can while at the same time tucking your knees up into you chest, hugging them with your arms if possible. Try and land gently on the balls of your feet. Limit the amount of time your feet are on the ground before jumping again.
This is a high impact style exercise, so if you feel any discomfort in you legs or knees please stop. Start with 3 sets of 5 jumps each, 30 second rest between sets. As your legs become more adjusted to the work out you can increase up to 15 jumps per set.
Great for building explosive legs strength for a verity of martial arts applications.
