Just being proactive, but if you're five pounds away from a hundred, go for that, not five plates. 405 is better than 400 because it's four plates. 585 is six plates. 600 is to far off to just jump to that. so when I see the five plate stuff, I'm thinking just be proactive and do 500.
As for pounds vs kilos, I do realize it wasn't brought up, but it's a slippery slope from five plates with 45s to five plates with 2o kilos. Next thing you know you'll be watching soccer and carrying a man purse.
My rules, go for a new 100 level if you never have. Go for plates at 2, 3, 4, 6, and seven. Never 5. 5 is so close to five hundred that you just do 500.
Man don't you young guys know these OCD rules that have been passed down forever?
