Often, golfers rush their warm up throwing their tempo off for the entire round. Start with an 8-iron and chip 20 or so balls off the front end of the tee (15-20 yds.) Do some basic stretching before and during these warm up shots. Force yourself to swing as slow as possible! After a couple dozen chips and pitches, progress to longer swings. Keep swinging slower than your normal tempo. Finish the warm up with a few longer irons and just a couple shots with the woods or driver. By starting slow in the warm up, a player has a better chance of developing a swing that has a good tempo for the round.
