anger is more than enough motivation for me IN the gym. Might not be a good thing but as soon as I enter the gym I hate ieveryone and everything.
I hate the silly trainers at my gym walking around puffed up and showing people how to do exercises wrong, I hate the other people at my gym for just coming to the gym to hang out and watch TV, I hate the bodybuilder wannabes with their invisible lat syndrome wearing a belt for every exercise (only reason they wear the belt is to look like they have a V-shaped upperbody), I hate the people looking at me like IM THE ONE DOING EVERYTHING WRONG. I hate the octagonal pound plates, I hate the shitty barbell collars and I hate the fact that I cant use chalk.
If you need motivation to even get to the gym I dont know how to help you tho..Anger in combination with some heavy metal/death metal is a great way to let out some steam on the weights. I almost knocked myself out a few times doing cleans, so if theres one exercise you shouldnt attack with pure anger its cleans..
