To sprint faster, work your hamstrings. They help you push off and develop speed. Try this variation of the leg curl: Pull the weight toward you with your ankles flexed (as you normally would) so that your toes are pointing toward your shins. But when you lower the weight, extend your ankles so that your toes are pointing away from your shins. Your hamstrings will work harder than with the traditional version of the exercise. You can also use bands instead of weights.
