Train Backwards To Boost Your Club Head Speed 

There is no peer reviewed published research available that supports the claim that non dominant swing training increases swing speed over dominant side training only. It’s therefore just opinion and is usually put forward to support a commercial product.

I swing backwards a lot and I can always tell it helps me tremendously.

I have used superspeed no-dominant backwards swings and dominant forward swings. I have used Superspeed for about 12 weeks. I also held on to the opposite end of the club where the weights are. My driver speed increased from 90 mph to 105 mph. My 7 iron speed increased from 74 mph to 85 mph. My sequencing is better. I also lifted weights to increase my basic strength, squats, dead lifts, arm curls, arm presses, lat pulls. Superspeed is the only golf tool that ever worked for me.
