Jump Squats

Jump squats are great to do for athletes looking to gain explosive power, especially for short distance sprinters anywhere from the 55m dash to the 200m dash. They work on the hip flexors and extensors, knee flexors and extensors and strengthen your calf muscles. They especially aid a runner in exploding out of the starting blocks. This improves the fast twitch muscle fibers due to the low repetitions and heavy weight and involves concentric contractions exploding upward and eccentric contractions in the knee flexors and hip flexors.
