You can also look up good workouts online that only require things like dumbbells, or even no equipment at all. I use Fitnessblender all the time, it's pretty good for mixing things up when you don't want to do the same workout all the time.
Working on the pole can feel like there are some pretty big strength jumps, but it really just takes a little craftiness to figure a way to make what you CAN do into something that takes you up to what you can't do!
Climbs, for example: I tend to use the strength of my legs way more than my arms, because I know my legs are strongest. However, I have been using this to my advantage to work my arms- I practice climbs, about 2 sets of 5 reps on each side right now, and have been focusing on pulling myself up with my arms, rather than just using the leg to step up onto. My leg helps, but it isn't all of the power anymore. My climbs have gotten much smoother!
For me, spins are also super useful, but they can be really difficult (and sometimes actually dangerous to the shoulder!) if you aren't quite there yet. Working on something like the fireman spin, for now, can actually help you increase strength in your arms, and help with creating momentum for spins as well.
There are lots and lots of other body weight exercises, both on the pole and off the pole, that you can do in order to help your arms catch up.
Also, Veena's lessons are online, so I'm not sure why you wouldn't be able to access them! Some of her workouts don't require a pole, either, and if you mix them with all the other things available, I'm sure you'll find a way that works for you!
And take care of your shoulder!
