What are the best exercises to increase my top running speed?
Locomotion science has proven that running speed totally depends on muscle support force at ground contact. To increase support force try leg presses where you lift the weight with both legs but hold with one leg, on ball of foot, knee sligtly bent. Hold as much weight as possible for 10-20 seconds. Do 4-6 holds on each leg a few times per week. Also run short top speed sprints to apply the support force faster. Lifting lighter weight faster doesn’t come close to the amount of force from sprinting. So lift heavy and do sprints.
