Fat at the gym questioning my lifting form. I got pretty angry about this. Basically I was deadlifting. I've only been deadlifting since November last year, and when I first started I hurt myself a little because I was still learning the form.  Because of that, I became super careful and made sure I was doing the lift 100% right. I spent so much time both asking people to watch my form and recording myself and analysing it later. I know I'm lifting correctly. So I'm in the gym doing my warm up set and some fat fuck is bench pressing in front of me. He watches me warming up then sighs and says "oooh you're gonna hurt your back". I look up and see this towering chunk of lard sneering at me condescendingly. Ham then proceeds to "show" me the correct form by deadlifting my warm up weight with a rounded back. Right now, I realised he was full of shit but I didn't want to be rude so I let him demonstrate and was hoping he'd go back to the bench.  Nope. Fatty stays until I do warm up, and then decides that my form is atrocious and that I need to do some bullshit squat-cum-deadlift move he made up in order to fix it. Now I've been deadlifting twice a week since my injury, and in that time I've not messed up the lift at all. I know I haven't because I've become a lot stronger. So right now I'm getting pissed off that this guy is demanding that I do this bullshit move, especially because he was an actual fat sack of shit. I mean easily 120kg monster. I then tried to explain to him that because I'm tall and have long limbs my deadlift form has to be slightly different than him (because he has chunky mounds of adipose attached to short stubby arms). I showed him how I struggle unless I use a slightly wider stance, and I prefer putting my hands inside my knees. And explained that shorter guys have to do the move differently because of range of motion issues. Nope. Fatty looks at me like I'm retarded then becomes insistent that I stop and do his made up crap to correct my form. I lost it right now. I should have said something but I just gave up my nice spot and went somewhere out of view to finish up (perfectly by the way) I can't deal with these fats telling me how to lift. If it was an actual big guy, maybe I would have doubted myself, but it was a marshmellow man.
