How much do you want to spend? I'm not the best with kg, but in lbs its generally:
2x 1.25lb (optional depending on linear program)
2x 2.5lb
2x 5lb
2x 10lb
2x 15lb
2x 25lb
2x 35lb
2x 45lb
2x 55lb (optional depending on strength level)
You can get a cheap set of iron weights.
Or you could get a relatively inexpensive set of bumper plates. (Plus some change plates).
I'm a fan of Titan Fitness' equipment. Its great for home gym use and the price is right. I have their T-2 series power rack and their 2" Olympic Weight Plate Rack Tree. I also got lucky and bought a bunch of stuff from MDUSA before they closed. I have 415lbs of bumpers, change plates, and a couple nice Pendlay olympic bars. That being said I started off with an inexpensive bar off of Amazon.
Hope this helps, I'm happy to answer any other questions.
I'm considering building my own power rack like <strong>this one</strong>. Materials are well under $200, I have all the tools and knowledge.
Any recommendations for Barbell and/or plates to use? I'm pretty set on olympic bar and plates vs standard, i'm just wondering if spending $300 on a rogue bar is worth it over something like this amazon bar for $100.
Also, for a power rack setup in a backyard on concrete, would you recommend bumper plates with no padded flooring, or padded flooring and standard steel plates?
