WATCH: The brutal Butch Harmon drill Tiger Woods hates and a lesson the average golfer can learn from it

From 1993 to 2004 Tiger Woods became the greatest golfer the world has ever seen while working with coach Butch Harmon.

These two have never settled for second best.

And in 1997 they rebuilt the Woods swing.

It would show that it was fruitful because when it was thrown, Woods was in control of the game like no one has ever been, but it was hard work to get there.

In this video it is no secret how much Woods hated the test that Harmon insisted on.

“This is an exercise I can't stand at all,” he said and spat out what followed: “And I can't stand it anymore.”

Woods demonstrates a drill: “Pull the club up, and stop, then come down, and hit the shot.”

“This is a plan that I have worked on for hours and hours. We were outside sweating, it was 100 degrees out there, we were both working hard, and it was something I had to do.”

While Woods gets over the bad memories of those hours of practice, Harmon takes over to explain his methods.

“The whole key was to put him in a high position where he felt that as he transferred his weight, his arms would fall down in front of him.”

Here's where it gets interesting, though, because there's a lesson to be learned.

“This is great for the average golfer watching,” Harmon said.

“Here's a guy who is the best player in the world, who hits more balls than anyone in the world, and it took him a year to feel comfortable with that movement.

“Despite hitting thousands of balls when a recreational golfer takes one 30-minute lesson from a local PGA pro and feels like he's got it!

“That tells you how hard he worked in this game.

“This man works harder than anyone I have ever seen. Greg Norman worked harder than anyone I've ever seen until Tiger came along and he works harder than Greg.

“And to be good at any level you have to put in the time. You have to work.”
