If you are struggling with your angle of approach this drill could be for you.
You can use this drill with any club you like. The only other thing it requires is a teed golf ball.
There are two different ways you can use this drill. If your swing is too steep you can use it to shallow your swing or if your swing is too shallow you can use it to make your swing more steep.
To start this drill you place a golf ball on a tee. If you want to make your swing steeper the goal is to hit the tee while striking the golf ball. If you want to make your swing more shallow the goal is to not hit the tee while striking the golf ball. To get the hang of this drill you can start with slower and shorter swings and then move on to faster fuller swings.
