Has anyone used a back brace of some sort that helps with posture and maybe belly support? I considered using my wife’s pregnancy band but also looking for other options.

My problem is that in the beginning of a round I have decent posture. My back is straight and not hunched over. As time goes on and I get more gassed out, my posture starts to suck and my gut / gravity takes over. This shows a lot in my scoring as I can play decent 1-13, but 14-18 is where I get gassed out and the posture goes to shit.

Hoping that there might be a back brace / belly support of some sort that I can wear while golfing to help with posture.

And before you gym junkies get on my nuts, yes, I know that I should focus on losing the gut to alleviate the back pain thus being healthier. But that takes time and I’ve got a tournament with money on the line in a few weeks.
