Showing off lifting a weight for a single rep is pointless. It won't build muscle, especially if they are fake weights.
Not in Powerlifting it isnt. Its what counts... Powerlifters dont care to look like BB's, just trying to lift the most for 1 rep.
But yes, if weights are fake, very pointless. Guy was strong as F**k in his day though.
At 220 lbs (age 30) he benched 515, Squatted 705 and pulled 640... Youll notice in a meet when in his 70's he pulled 515.
Still very strong, but not 700+...
