I have two questions for the vets here:
1) If I see a dude working out and his form is horrible - I mean the worst I have seen - and it looks like he is going to f*ck himself up because of it, should I say anything to him? I don't want to be a jerk to the guy, but he is lifting way to much weight, arching his back a lot, and is in for some hurt.
2) Less of big deal, but there is a dude who clearly does not wash his workout clothes and he stinks something awful. I'd guess that if you are within 20 feet of the guy you smell him. Is it bad gym etiquette to say something to him about it?
If I should just mind my own business I will, but I wondered what the right thing to do is.
