No matter how much you exercise, there is a good chance that you are not targeting the right muscles in the body. You can do as many sets and reps of the same things in the training room, but you are still not targeting the right muscles that will help you increase your speed. The hip flexors are a series of muscles that you might not think will help you with your speed but they have been proven to do so.
“Squat racks, hamstring curls, leg extensions, leg presses, glute kick backs, lunges, etc. all target the hip extensors, leg extensors and calf muscles.”
