If you play a lot of golf, you end up walking a great deal and this can tighten up your calf muscles. Doing a simple calf stretch on a daily basis could help you prevent injury.

Stand in a splint lunge position with your front leg bent and the back leg extended.
Press the heel of the back leg into the ground as you extend your leg to feel a stretch in your calf.
Hold the position for 8 to 10 counts and repeat on opposite leg.
