Thanks Depalma. And actually, the racks were perfect, bc I knew even less of them than I did the bb and plates. When Fru suggested, my question was why, and then Meg/Mel answered saying that you easily get to where you cannot lift it up over you to begin squatting, but that's the part I missed. I thought I could just load the plates on, lift it and bench, w/o realizing I'd be in the same problem of not being able to lift something that heavy. So the rack serves the purpose of holding the bar and letting you stack the weights one at a time, and then slide under it to start the squat, thereby you never have to hoist the full thing off the floor, correct?
I will have to see what I think. Strangely enough, the gym about 2 miles away had an open house today. I didn't get to go bc dd is sneezy, and nothing would be worse than taking a sneezy kid into a gym with me for a tour! I have to weigh out options - since I already have a treadmill, elliptical, free weights, and enjoy working out at home and don't have alot of free childfree time (and don't want to drag my kids into gym daycare), I may continue to add on at home. The cost for more equipment would probably only be about the equivalent of 4-5 months of membership anyway...and then be mine to keep. I really don't want the gym for any classes at this point in life. I really like being able to work out at 6 am or 9 pm while my kids are sleeping if I want to, plus on the weekends while they play in the house w/o making them have to go somewhere with me. Hmmm, I appreciate all the links, I feel like I had a virtual class in racks. Thanks again!
One other question - are there any other moves I'm likely to "outgrow" and need more gym type equipment for? I don't necessarily want to do assisted pull-ups, leg presses (Mel says they're overrated, and not to worry!

) or fancy things, but want to continue to develop. Are there any other exercises that I will run out of growing room just using free weights with?
