You do not need both throws on day one. You need one throw you can trust, and a simple plan for the other. Here is how to choose.
Learn backhand first if…
You want the most common, most versatile throw in the game. The backhand is the natural starting point for most players and it teaches the fundamentals of timing and rotation.
Start with standstill throws and a midrange or putter. Add a small walk-up once you can throw flat and straight.
Learn forehand first if…
Your body prefers a flick, you play a lot of tight wooded holes, or you want a shorter learning curve to controlled approaches.
Keep the wrist loose, finish pointing at the target and resist the urge to throw hard. Touch and repeatability matter more than power.
The quickest path
Learn to putt first. A reliable putter saves more strokes than a perfect drive, and it makes every other part of the game more fun.
Then build one dependable throw. Make the second throw a project for next month, not next round.
