You can read in numerous posts to practice away from the course, but practice what? How?
What drills do you do that have improved your game on the course?
Here's what helps me:
5 putters (same mold)
1. Alternate shot away: Starting at the basket, throw your mid-range discs mainly for distance using an alternate throw. (If you normally throw backhand, throw sidearm) This helps you learn an alternate shot while placing your upcoming approach at a realistic range
2. Prefered approach shot to the basket: Throw each of the midrange discs from where they landed back to the basket using your prefered shot.
3. Putt: Try to make a sucessfull put with each of your putters for each of the approach discs. (If you have 5 approaches and 5 putters, you will make 25 putts)
I'm now feeling comfortable enough with my sidearm that it is finding its way on to the course.
As your alternate shot improves (and you get more distance), your approaches and putting MUST improve with it.
There's my favorite,
What drills, routines, have helped you?
