What do you call this weight training equipment? Where can I find it?

First off, what do you call these things:

– A rack of sorts for bench press, incline press, weighted squats, etc. It has lots of holes with an adjustable metal piece you can pull out for resting a 45lb Olympic bar. You can set it at a low height for bench press, medium height for incline press, and other heights for other things. It is used for racking an Olympic bar. What is this called?

– Where can I find one of the aforementioned items or racks, whatever it is called, for sale on the internet?

* Where can I find an Olympic bar with 45lb, 25lb, 10lb, 5lb, and 2 1/2lb weights for sale? I am willing to buy the weights separately from the bar, but I would like to know where I can find them for sale on the internet or in a physical store.

~ Where can I fend an adjustable bench, which I can use for bench press, incline press, and other things?

So yea I’ve been looking for all this stuff, but as usual I cannot find most of it. I checked sports authority, that is the only store I know of. I heard of this store called Dick’s sporting goods but I can’t find their website. So any help is great, thank you.

what your describing sounds like a power rack, power cage or squat rack among other names…

most normal sport stores don’t carry olly bars in stock but most are willing to order them in for you.
