Generally speaking, you don't wanna mess with any fat ass, in terms of pure strength anyway.
I'm almost 6' weight at 145 lbs, workout daily, maxed out benching at 335 lbs (i.e. 3 plates and a ten on each side), can curl up to 50 lbs on biceps and I'm no match to my 220+ lbs fat ass friend in arm wrestle. Literally KO me within seconds.
There's no replacement for displacement, humans and cars alike. :biggrin:
