With such a topic so broad we truly try to cover the basics from all angles in this group. Nothing too big or too small. Nutrition is as significant if not more as exercise is to reaching your goals so learn all you can.
have any of you ever used one i just had one given to me, all i am trying to do is firm up and loose some weight, i do 2 miles of walking 6 days per week also for the weight thing and health purposes
If this helps, one of my clients has one and wanted to train exclusively on it, not a gym. It really proved to be a very versatile piece of equipment, and worked rather well for her needs. You can simulate most gym exercises on it with no problem.
