straighting right arm at impact

[tmf9]

Some days its worse than others but I am fighting my right arm straighting at impact causing me to hit off the heel. Does anyone know any drills or tips that help with this?

One thing that I found to help with this is using a nice easy tempo. The trick is to not swing hard and keep the right elbow close to the body at impact. Once that happens, your left arm will naturally rotate along with your right and your right arm will extend. Just take the follow through down your target line.

I like to go to 1/2 swing when I can't get good contact going. Hit about 20-30 at the range 1/2 swing then another 20-30 3/4 swing. Then when I feel confident I move into the full swing.
