I suck at spin mode – just prefacing with that.
Here’s my 2 cents on the whole thing – first please be sure that pole is tightened before going into spin mode as I have had poles come down, seen poles come down after extended use in spin mode – so be checking your pole.
Secondly, as V says don’t work on inverting on spin mode straight off. Work on your basic spins
Extending your body/limbs makes the pole slow down, pulling your body into the pole makes it go faster. It’s pretty tricky keeping a spinning pace so work with it. Many dancers will let the pole stop spinning while in an advanced move and use either the ceiling or the floor to spin them when they are ready to spin again.
Rule of thumb is to decrease your momentum by 50%. So in the beginning gently push off the floor into your spin or move.
Spin mode is great for building grip strength and your upper body, but be cautious because it is a little more dangerous and you have to be really present and in the moment while working with it. It’s also a good idea to use spin mode when you have a lot of space, smaller spaces can be more difficult because extending out to slow down the pole can be harder and you can hit yourself on desks, chairs, etc. LOL! I know I have more than a few times. It can be hard to get your bearing in spin mode.
With time you’ll get better at finding a more stable spin speed.
