good point, but in my case i don't have the room...and i'm the only one who uses it so its not like i'm taking up a power rack at the gym while someone waits for squats
my "home gym" consists of a 10 year old weider bench w/ leg attachment, some adjustable dumbells, a 15 lb bar, 250 lbs of weight. my squat rack is 2 chains hanging from the ceiling w/ a hook on the end to rack the bar.
