You cannot spot reduce (unless you want to get surgery) but you can spot tone.
In order to reduce that wobbly thing, you'll need to lose fat overall... Cardio, streght training and being mindful of what you eat (and drink) is the way to do it. Personally, I don't think pole provides enough cardio. You cannot be pole dancing non-stop for 1 hour, like you do when you run or cycle. I would recommend you added 3 cardio sessions minimun to your pole routine, maybe start with 20 minutes, but you want to do at least 30 per session, ideally longer (40-60min). You can also play with the intensity, do shorter, more intense workouts, interval training, longer, slower pace sessions... I recommend running, since it has many other benefits for women and you can do it anywhere, but please check if it is right for you.
Besides, you may want to increase your core work. If you do Veena's routines, you may want to add more reps or weights.
But keep in mind that each body is different and it may be difficult to change... our genes control our shapes. I know I will never have skinny legs If you have improved overall, that may be more than enough! Wanting to improve is very legit, but always love your body 💕
