The sklz acceleration trainer shown in this video allows us to provide heavy resistance during sprints. The release function adds an overspeed element to the sprint. Speed training is a grind. You either go 100 percent or leave. You can't hide behind the dumbbell rack or some machine in the gym. That's why we make this type of training a main focus of our summer programs.
