It’s important to keep the clubhead outside of the hands on the take-away. Place an alignment rod directly behind your ball on the target line. Take a swing about a quarter of the way back and check where your clubhead is in relation to your hands. The clubhead should be closer to the alignment rod than your hands. A common fault is to only use arms and hands on the takeaway. This can cause you to suck the club to the inside and will leave your hands closer to the alignment rod. The swing needs to come from the large muscles. Focus on keeping your arms and hands quiet and using your core to initiate the swing. Let the clubhead travel down the alignment rod in the beginning part of the swing.

A metronome is a great tool to help you with rhythm in both the full swing and short game. You can download a golf specific metronome onto your phone to use when you are practicing. It will allow you to find a tempo that works best with your swing or stroke. Most people tend to get too fast in either their take away or at the top of their swing. Find a beat that works for you and then incorporate it into your tempo. Start your swing on a beat, reach the top of your swing on the second beat, and then reach ball contact on the third beat. In putting, use four beats. The first beat is a look at the hole. The second beat is bringing your eyes back to the ball. The third beat is the start of your stroke. The fourth beat will be at the end of the stroke where you should hold your finish. This should help you get a consistent, smooth tempo.
