Maybe not totally necessary for golf, but you're right, and olympic or compound lifts are THE BEST thing you can do for muscular and skeletal health if you are concerned with strength, speed and power. And no, you don't have to use huge weights, or get bulky. There are some sexy slender women who use olympic weight lifting. If you want more power and distance, do not ignore these lifts. I think deadlift and snatches would be the best for golf.
