Get your glutes and hamstrings active and warmed up.

It is very important to get your glutes, hamstrings active and warmed up before fully going 100 mph. Golfers generate power from the ground up. So I like to do a simple bend over and touch your toes for 35 seconds. Then go to one leg up on a bench stretching towards your toes, switching sides up 35 seconds. Do that for about 3/4 minutes.
