15 kg/ 28mm bar, 30mm bar (thick) Deadlift

[newtoss2022]

Been using a home gym, and i am using the 15kg to squat, and slightly thicker bar on deadlift,

Question: Does this 15kg bar would affect my strength training in squat/bench?

Currently doing SS
5RM - 305

The 15kg/25mm bar is a women's Olympic weightlifting bar, not a strength training bar. You didn't mention a 30mm bar.

there's a lot of weird shit out there these days.....thanks to: 1-crossfit, and 2-globo-fitness-corporations + how mass-manufacturing is so easy these days. And now this junk is floating around all over the place (as the box-gyms go BK).

Rogue makes a 15kg/28.5mm bar, and a few other weird designs. Same as an Ohio bar but much shorter sleeves.
Something about being more compact/shorter, for group classes where you have say 25 soccer-moms and dad-bods working out in close proximity to one another in troop-formation thing.
