Power Cleans

Power cleans work the lower back, knee extensors, trapezius, and hip extensors. This can make one more explosive coming out of the blocks in short sprints and a stronger, more powerful runner overall by performing these with heavy weight and low repetitions. This will help increase the effectiveness of the fast twitch fibers which enable a sprinter to perform at high speeds. This exercise involves concentric contraction when lifting and eccentric contractions when you drop down into the squat.
