I worked out at home up until a month ago. All I have is a power rack equip w/cables, a bench, weights, a straight bar and a pair of barbells. If you are disciplined enough there is no reason why you couldn't make mad gains at home. I went from 170lbs to 220lbs working out in my garage. I will tell you that when I joined Golds last month it jump started my training.......I don't know why, maybe the change in atmosphere but I have a whole new addiction now. By the way my wife bought the set up for me and spent less than $1000 3 years ago and it is a quality set up. If you shop around you can get good quality equipment and not spend your left nut on it.
