About a month ago I posted about not being able to get the weights over my head when doing squats, and got some good help. One tip was to look into getting a squat rack.
I’d agree with Phill on the power rack. Unless you are always going to have a spotter, the Power Rack will eventually save your life. You can always add the Pulldown station later. Or you could just get some bands to do an assisted chin on the pullups.
If it is a quality piece, then the price certainly looks right.
