Hello

I’ve had a pole for 6 weeks and I have the exact same problem. I’ve realized that’s the reason I used to slip straight down was that I was a bit overweight and plain just too heavy for my own grip. After 6 weeks my hands have taken a lot of blistering and healing and now have started to become hardened and I can do one armed spins fine. also I found hanging off the pole really helped and so did attempting to climb it.Ive become a lot stronger! hope your friend improves!
