I've had 'bad knees' for years. Never got anything diagnosed but know that added weight has not helped. Have started a gym programme of cycle, treadmill (walking only), thigh expanders(!) and swimming. At the mid course meeting I admitted to the gym instructor that I was struggling because of my knees. She seemed slightly puzzled as to why this might be. The advice eventually was to layoff the treadmill and take up the aqua class but to also go and see the doctor. This is what I have done. Doc reassured me it was just wear and tear and that it was probably good not to do the treadmill anymore. The aqua class is a joke. The instructor has the worst sense of rhythm I have ever met!! Honestly, I've done aqua aerobics before and have been a keen dancer in the past. She makes us do exercises in the water, mainly leg, that have very little structure other than to make my muscles very painful ie too many of the same exercise for too long (hope I've explained that correctly). I've been for x-rays and wont get results until next week. Meanwhile, I really don't want to be taking painkillers all the time (docs advise) but I have to have my right leg straight for as much as possible - sitting at the computer now makes it very painful when I stand up! Also going down stairs is very painful. I don't really know what I want done but if anyone has any advice I would really appreciate hearing it. I need to do the exercises at the gym etc so that I can lose weight - which is very slow going at the moment. Thanks for reading this post. Help!
