We all know golf legend Gary Player is a fitness freak, but we didn't know how far he would go to prove how fit he actually is.

According to an article written by LPGA player Michelle Wie for Golf Digest, "Mr. Fitness" himself once approached Wie and dared her to punch him in the gut.

The result was pretty ridiculous (h/t to Kyle Porter over at CBSSports.com):

"I was at another event with Gary Player. Out of the blue he says, 'Michelle, hit me in the stomach.' I didn't want to punch him, so I kind of poke him instead. He says, 'No, I want you to really hit me!' He widens his stance and clenches his stomach. Now I really hit him. I'm no fighter, but I hit him as hard as I could. It hurt my hand. It didn't faze him. He pointed to his stomach and said, "A thousand sit-ups a day" and kept walking."

I don't know about you, but Player gives off a 'weird old muscle guy' vibe because of stories like this. At least he didn't try to tell us he could throw a football over those mountains.
