First, add the barbell on the bench press to a weight that is very large for most people, generally between 120~ 140 kg; Lie on the bench press, get out of the bar, put it on your chest, stop and close your eyes; Some people think that it is impossible to push it up and get crushed, so they come to help and stop it quickly: "Nothing, I just have a rest and feel the weight." Then push the barbell up as quickly as possible, put it back, sit up and say, "It's time to rest." Leave the gym.
