This isn’t really answering your question but if you don’t have a barbell(or if you want some variety) or anything you could make a chain press. I saw it in the bodybuilding forums a while back and buddy had a neat idea. Take a chunk of pipe and hook a chain to it. on the other end of the chains, attach some buckets full of heavy shit. use different chain lengths for different lifts. I thought it was kinda cool. There’s some other at home training ideas in there as well.
