It feels like a paradox, because it feels like I can make a club swing faster with my arms than with my body, but it doesn't translate. Obviously involves both to a degree but I cant seem to find the sequence yet. Sucks about lockdown, will focus on my fitness and flexibility for a while, as wont be able to see ball flight.Most higher handicappers are guilty of this Jus...decelerating at impact...flipping their hands early and losing any stored up energy they might have created if the have a decent backswing and pivot. Using hands and arms trying to create speed. If you hit the ball fairly high...and not too far...that flight is telling you pretty much that. If you hit the ball lower with decent penetrating distance you are more likely keeping lag...reducing your loft. I find it tricky to work on that stuff honestly (impact)...everything is happening so fast at that point. You think you are doing something but may not.
I see in your other post you are struggling a bit not being able to practice atm. Back in my day (LOL) there were no driving ranges for blokes like you and me (different at the private clubs).....getting a golf lesson was not a thing...there was no internet. All this stuff helps but confuses us a lot. We just went out and played for fun. We managed to get to a decent level (I got down to 10 without any instruction and no idea)...albeit with flaws, which I still struggle with a bit nowadays.
