I know everyone has a way they like to warm up before playing a round.  Me personally, I like to hit a variety of shots, from full shots, to wedges, to bunker shots, and a few putts.  
My question is how do you guys warm up?  Do you like to set a certain amount of time to practice certain shots?  If so what types?  Or how many balls do you like to hit with each, etc.  
I am open to hearing how you warm up, and maybe adding ideas to my own routine!
