Hey there!
Many, many people begin pole without being able to even hold their weight up off the ground, in any position. This can be super difficult, and depending on how you have your shoulders engaged, sometimes a little straining ;)
With Veena's 30 day takeoff, she'll have you do rest days, which are super important! You heal, and become stronger, during those rest days. Appropriate maintenance and care of your muscles will also help you heal up a little faster- things like foam rolling, having an epsom salt bath (probably would be lovely for some "you" time, too!) and even having a shower where you alternate hot and cold (seriously, I tried it! Not so bad, and it helps keep the muscle soreness away). And massages, if you can afford them ;)
Most people find that working out 3 times a week is best for them- often, this is all we can spare! I would say that a maximum of 5 times a week, and a minimum of 1 time a week, and you would still see progress. Obviously, faster progress with more workouts, but you also want to take into account your energy levels, and your time constraints- are you actually able to muster that much energy five times a week? I know I'm not able to, and I don't even have children!
You don't need to have worked out before you start pole dancing, as Veena has it all laid out in order- you start at the beginning and work your way through, slowly! Listen to your body, and find out what it needs in order to do the move safely, without any stress or strain, without throwing yourself into it fast and uncontrolled, and you'll be well on your way :)
And welcome to the site! :)
