You are swinging with the arms and not clearing your right hip. Thats the bottom line

Try this little test.

-Stand with your belt buckle facing forward (12pm) and swing your arms. Look how they have to go round and in front of your right hip

-Now stand so that your belt buckle is facing 10am and swing your arms slowly .. see this time how your right hip is out the way and there is an inside 'lane' down which your arms can travel from the inside

I tried for 5 years to try and find a way of not coming OTT whilst being a hands and arms swinger. Its impossible

You have to learn to give up control of the downswing to your lower body and keep your arms and hands as soft as possible. The thing that worked for me was the feeling that I tried to hit the ball with my right hip. Think right hip as the thing that moves first in the DS. If you can do this you will feel like you are going to hit the ball way left because it will seem like you are so open at impact (see Gregs impact drill) but you wont IF you keep your arms and hands soft (this is what builds lag). If you can do this and you hit the ball left its because you are still fighting that urge to turn your hands over as a legacy of the OTT move. If you hit pushes thats better but thats because you are still holding on too tight and not trusting yourself to let go

You will have to hit a lot of balls to get out of the habit. It wont happen overnight so accept that. If you find as you get that lower body turning first with soft arms/hands that you arent getting immediate results dont do what I did and go back to swinging with arms and hands again as you'll go back to square one. Theres no miracle cures in this game, it takes time and patience

Good luck mate. And keep at it .. the desire is obviously there and thats ta great thing
