When I first started pole I had no upper body or core strength whatsoever. I was so weak that I couldn't even get in to some of the poses, like split grip, to build on strengthening the muscles further. I started taking TRX classes, which really helped to build my strength. After a few months of that, I started lifting weights at home. I have a great book called "Strength Training for Women: Tone Up, Burn Calories, Stay Strong" by Joan Pagano, which taught me the basics of weight training. I've also used YouTube a lot for learning different core exercises. And since then, I've started taking Body Pump classes, which are amazing! Very difficult, but in an hour you get a whole body workout. My muscles are usually shaking, they are so fatigued at the end.
Weight loss is going to be more about changing your diet, since it's about 80% what you eat and 20% exercise. I've used calorie counting myself with success in the past, and I like the My Fitness Pal app for counting calories and their website with its message board with lots of support from other members.
Good luck! You can do it!
