My mom rants about it and says I have scoliosis. But I'm sure I don't, I played sports and we had to bend over and they checked my back and they said my back is fine. I'm in tumbling, which is a form of gymnastics. I use my legs a lot but my arms are really weak because I barely use them for back tucks. I'm on the computer a lot, so that might have caused it. My shoulders always roll forward and I end up looking like a hunchback. I don't even notice it because it's comfortable for me. But it's unattractive and I want to fix it! Just keeping my back straight doesn't help because I'm unaware a lot. I feel like I need exercises and a doctors help. What do I do?
