Reddit User u/b_dub79• r/GarageGym

I've got 705lbs in steel plates and 350 in bumper weights. The steel plates are my go-to for anything inside the rack - squats, bench, overhead press. They're thinner so you can load more weight, and they don't bounce. For deadlifts and Olympic lifts, I use the bumpers ^[3].

Discussion on weight plate material preferences, garage gym setup

Reddit User u/housepantalones• r/GarageGym

Just checked Walmart.com - they have bumpers for 60-80 cents/lb, and cast iron plates are about the same price. The price sensitivity in this market is really high. Most home gym owners are watching every dollar ^[4].

Discussion on weight plate pricing and where to buy, 8 comments

Amazon Verified Buyer• Amazon.com

Great value for the price. The plates are well-packaged and the weight is accurate. However, the center hole had some burrs that scratched my barbell. I had to sand it down before use. For the price point, it's still a good buy, but QC could be better ^[5].
