I’ve made huge strides since my private lesson back in December. Two things still plague me however
: my lead knee turning in instead of down in the backswing and this. Can’t seem to keep my lead arm straight on the downswing. The picture on the left was my normal swing. The picture on the right is when I started pushing away with my trail arm. It made it 10° straighter but I’m not sure if this is the prescribed solution or just a band aid. Anybody want to chime in on either of these problems please throw it at me.
Have you tried to start the backswing only with your shoulders.
Next idea is to tug your trail elbow at the ribcage more in front. Cant see the position of your elbow clear.
