As far as strength, when I started pole over four years ago I was very active with regular gym workout, did interm step aerobics, an awesome powerflex weight class, etc. None of that made a difference with pole, it was as if I'd never worked out before. Pole was a whole different world and I had to start all over with strength building, etc. I couldn't do a pole hold or anything. I kept at it and strength came. I remember having the deer caught in the headlights look for new spin or trick LOL
The hardest thing to learn was taking my time to develop strength and not rush to do something I wasn't ready for. Thus, had to stop for a couple of months due to seriously pulled muscle in rib cage attempting basic invert by kicking into it. I actually thought I fractured a rib. I share this, not to scare you, but encourage not to rush, more importantly don't compare yourself to others.
Unfortunately pain is part of it as you and your skin get used to a new spin/hold/trick. I've accepted I may not get everything and doesn't matter what others are doing; and if I'm doing the same thing over and over, that's okay as long as I work at it getting better, etc. That being said, can't wait to see your journey and happy dance with you as you begin accomplishments :)
