Digging up this old thread
I was recently given a spinner, a metal one. My coach showed me how to use it and made sure that I would practice on it every day.
My problems are pretty much everywhere in spins- approach, sweet spot, balance, core position, et cetera. I can definitely feel my body getting out of alignment and my balance being lost while on the spinner. I also have the same open-hip crossing foot problems on the spinner as I do on the ice, so that's something I can work on.
Also, if I drop my heel while on the spinner I instantly stop, because my heel catches the floor. I drop my heel a lot when spinning. On camel spins, sit spins, back sit, backspins, dropping my heel causes the spin to spin in wide circles or three-turn onto the wrong edge. On scratch, rocking from heel to toe causes traveling. So if I can learn to never drop my heel while spinning on the spinner, it should transfer to ice... right?
Since my coach thinks it'd benefit me, I see no harm with going ahead and practicing on it everyday.
