Try out some grip aids, here’s a nice handy list of some…

Mighty Grip – a powder which is activated by heat
Gorilla Gold – a sticky towel
Surgrip – the wonderful "mythical" stuff, they’ve stopped making it now https://www.studioveena.com/img/smilies/icon_e_sad.gif
Dry Hands – I love this stuff
Eco ball – a chalk ball
Liquid chalk
Stickum – a spray or a paste
Itac – level 2 is recommended for pole dancing

It’s best not to get reliant on these grip aids, but they are wonderful for learning new moves, especially if you’re anything like me. As soon as I try anything new I get really sweaty hands
