yeah belivable.
one thing. you got the kg/lbs numbers wrong. 140 kg= 315, 180 kg= 405 ..the other are abit off to.
Maxx, you're a little confused bro. In the UK we generally have 20kg plates in the gym. In the States they have 45lb plates.
315lbs, is 3 plates a side.
140kg is also 3 plates a side....however the kg/pound conversion is 2.2
20kg times 2.2 equals 44lbs, (not 45lbs).
So; 6 x 20 (+ 20kg bar)...multiplyed by 2.2 = 308lbs.
Hope this helps.
