Hard bump on this sort of old post in case anyone besides me wants to brag about their home gym or vent about not having one.
Misanthropy, introvertedness, antisocial tendencies really pay off when there's an apocalypse. I just keep doing the same thing I've always done.
I'd estimate maybe 900 sq ft of my unfinished basement is dedicated to random gym equipment. Got a decent safety squat rack, terrible set of about 365 lbs of cheap metal weights, along with a bar that will break long before it will bend. Typical all in one thing for tricep pulldown, flys, smith machine stuff. Rogue Ohio bar for deadlifts, 405 lbs of rubber bumper weights (should have got more so my deadlifts aren't part rubber weights, part metal weights), standard deadlift Jack. For cardio I have an elliptical, treadmill and recumbent bike. Then some awkward assortment of dumbells. That's about it.
I was in some of the rogue groups on Facebook for like a week before that got boring. Quite a few guys out there with $35k in home gym equipment, sure they're hamming it up now.
