Zach Johnson is employing quite a training program to get himself ready for the 2019 US Open, and it's involving some classic negative reinforcement to avoid missing putts.
In preparing for the week at Pebble Beach Golf Links, Johnson was practicing putting on Tuesday. Whenever he would miss a putt on the putting green, he would have to drop his putter, walk off the putting green, do some jumping jacks and then get back to work.
Johnson's caddie or coach would pick up the putter, hand it back to him and have him try to make the next one.

I'm not really sure this is the best way to convince someone to not miss putts. After all, there's no requirement to do jumping jacks if you miss a putt during a golf round. And unless he's going to commit to doing them during the actual US Open, I don't see the point.
Nevertheless, the two-time major winner is trying to get back to the form that won him the 2015 Open Championship, and if that means a little physical activity to stir him up, go for it.
