I was in the same boat. I'm 5'9-5'10" and was 183 pounds. I wanted to try pole lessons at my town's studios so I did an intro class. I was so discouraged. I'm a horrible person for always wanting to know I'll succeed at something before I'll try it. Our instructor did her demo and I fell in fan-love with her, her talent, strength, body, sassy, comfortablity with herself.
So I saved for a beginner's course (I did it 3 times) and after a year I'm getting comfortable about the whole thing and my skill status. Some things I'm great at, other things I excute like I've never tried to do it before and am wear 100 pound weights on me. I'm saving for a pole that fits my new high ceilings, mirror, and a recording device, I've decided that will help me progress and not feel awkward to 'dance for someone' and have them critique me.
I didn't have a pole at first but I did watch a lot of pole video's on YouTube, and did a lot of goggle searches on basic moves. Dirdy Birdy was my first fav instructional videos, studio veena has been the best overall.
What I knew I couldn't do were push ups and pull ups. So I would time myself for 30 seconds to minute how much I could do, and I recorded it, and recorded feelings of success or 'failure'. This has HELPED me see progress and feel progress.
For me diet has been my number one challenge. First I ditched the scale, I made a diet goal, like one week no soda, next week more water or only drink water. And progressed with eliminating bad adding good choices. Sometimes the goal of the week was to maintain the great progress I was making.
Keep a journal or blog, just make some time to track week to week goals and excutions and feeling/ thoughts on the success or 'failure' of it. Make other life goals, like: when I look at myself in the mirror, see what I like in myself versus what I don't like about myself. Or another one that helped me; compliment at least 3 people today. If you're busy focusing on overall improvement, mentally, emotionally, physically; you could see yourself differently and for the better. You might not be your fav pole star athelete right away, but you will be happy to work towards making more effort in pole and happiness.
Cheers to you for choosing pole as fitness and a damn sexy hobby.
