Except when I do squats. I tend to get lightheaded and faint when doing these. It makes me mad, because my legs feel like they could keep on going. But I must do the first set of 15, stop a while until I feel better, do maybe 8 more, stop again, do 7 more. Maddening.
I ended up not going for a week, due to being out of town. I am going to try to get my grandfather's weights he doesn't use any more and carry around in my car since it looks like I will have to travel for work indefinitely.
About the topic, most fat people are not going to learn weightlifting from a fat instructor, because most fat people don't know about/don't want to do/have misconceptions about weightlifting!!! So the only place they are likely to see a large instructor is the aerobics floor. On the NAAFA board I only have seen one other person who does any weights at all. But any who are exercising are either swimming, or doing some form of aerobics as able.
