i am impatient to watch all the clip..lol, it is just damn bored. bored slang
haha

it is common, that we can hardly see people squat in gym, even they did so, that will be partial squat.

if you go and tell them squat deep, they will replied you:" no, it is bad for knee."

and if you see someone sitting on the pull down machine, they will probably doing back pull down. if yo go and tell them that is bad for shoulder healthy, they will replied you:"oh..." and continue doing.

So just shut up and squat, unless they ask for opinion.

huh?
