"My friend puts one hundred seventy kg on the rod while doing bench press."
"Please put ten kg plates on both side of the barbell rod."
"I am putting ten kg plates on the barbell rod for this set but on the next set I will take out ten kg plates and put twenty kg plates on the rod."
I am not a teacher
Weightlifting's not my area of expertise but I'm pretty sure I've heard "My friend can benchpress 170kg".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
In AmE, we'll even shorten that to just 'bench'.
I can bench 350 lbs*.
