WATCH: Gary Player sprinting on a treadmill is the motivation you need

The nine-time major winner is likely fitter than you are

The fittest man in golf is not Rory McIlroy or Dustin Johnson. No, it is 81-year-old Gary Player who claims he does over 1,000 situps a day and clearly stays in tip-top condition. This video of him grinding out some treadmill time is proof of that. I'm 31, and I'm not sure I could book it as quickly as Player does here.

The look on the man's face next to him is also pretty priceless. As if he has no clue that this crazy man next to him has nine career major championships.

The Black Knight tweeted the following bit of encouragement to those of us prone to sitting on our butts.

It's important to train your mind and your body to move fast as you age. Don't give yourself limits. Keep working. Keep moving. pic.twitter.com/GDHLRWqsAC
