Thickmadame, I totally get it. I have arthritis in my knees, and my right hip, with torn cartilage in my left, so I understand the limited mobility. I’ve been told, and have experienced previously that weight loss is mostly about food. I use to be 310 pounds, and I got down to 210 by just eating right. That was when I was 19. Now that I am 25, and back up to 270, I’m finding that things get a little harder and different. I’m going to be starting a blog about living healthy and coping with pain at a young age where I will be trying out certain things that help reduce pain, but also help lose weight, so please stay tuned. I’ve lost weight before, I can definitely do it again!!! Even though sometimes I feel like giving up. In the meantime, swimming, water aerobics, and a stationary exercise bike will be great! Don’t try to do what your body does not like. Yes, zumba is fun, but our bodies can’t handle it. And that’s ok. That is temporary. Once we build our knees and hips back up, we’ll be able to do it again. So just try those things for now, and see how it works, especially the swimming. But if you swim, make sure you eat before, or after. It is very draining! I hope this helps. I need some advice myself. Some days I feel like, “what’s the point?” But I know there is one. 🙂
