Has anyone quit the gym to workout at home and been successful at it? I joined a gym several months ago, because I have a couple friends who go there, but each month I find that I'm going less and less. I like to do group exercise classes, but a lot of the class times don't work for my schedule. Plus, I have to bring my kids with me when I workout, so that adds another level of planning. The gym isn't cheap, and I'm wondering if I could save that money each month by working out at home and streaming online videos, but I don't know if I'll have the motivation to do it without a live instructor and others working out with me. Has anyone made the switch and made it work? Any thoughts on which is better?
