So doing 5 reps is near max 
Do you care to bet on me getting 275 in October at the meet?
I'm up for it😉
I am cock sure that I will smoke it💪💪💪
Just like the cock suredness of this drum beat
OH YEAH!!!!! YEAH!!!!!!!!!!
I would never bet with anyone I wasn't sure had the ability to pay.
However, if you're using a weight you that is absolutely taxing you, your body will convulse like that.
So, call it your five rep max, I don't care.
