I’m sure the advanced girls will have loads of great advice-everyone is really helpful here. But I swear it gets less painful over time. There are lots of times I can’t get that grip with my thighs and I slide right down the way you’re describing. When I REALLY can’t get it, I shrug it off & try again the next day. Sometimes it’s more about your body chemistry and the weather than strength or technique. I’m sure you’ll be writing about your success in no time at all.
