…well, not an entire day, more like 90 minutes, but you know what I mean.
1. Swing practice. Practice hitting the ball straight. I say that because that is really all you can practice. Unless you are under the guidance of an instructor, it is very hard to practice hitting the ball farther. Most likely your attempts will take you in the opposite direction.
Missing the green to the right or left is what you want to take out of your game. If you’re always too short, solve that problem by using more club or move up a set of tees.
Start out hitting some decent 9-irons. Now use that swing with the rest of the clubs you hit to hit the ball straight. The longer shaft and lower loft will send the ball farther.
2. Practice the things that make your swing work. Practice the parts. Put them together and hit a ball. Repeat many times.
3. Save about 20 balls and practice hitting long chips/short pitches, whatever you want to call them, of 15-40 yards. This is the shot pros are insanely good at and that we are insanely bad at. And it’s not that hard to get good at it if you practice. Down in two from that distance is an attainable goal you should have for yourself.
4. Green reading. I read putts from about 30-40 feet behind the ball. That way, you can see the overall tilt of the green very easily. You can sees slopes in ground that up close looks flat. I even look at two-footers this way. You can miss two-footers if you think they all go straight in.
5. Green reading. I start by imagining where the putt would go if I hit it straight at the hole. I follow it across the green in my mind and notice how far to the left or right I think it will pass by the hole. My aim point then is that distance on the other side of the hole—if my mind’s eye sees it miss three inches to the left, I start the putt three inches to the right.
6. Watch this Phil Mickelson putting video. Was he says to do WORKS.
