You're seated at the lat pulldown machine, you pull the bar down behind your head rather than to your chin/collarbone area. Good or bad ?? I have read articles that suggest this is not good to do. Personally, I prefer chins over pulldowns. The few times I do pulldows ( for a change) I pull to the front. Any opinions ??? Also, I saw a guy at the gym today doing pullups and he was pulling up to behind his neck. Looked a bit scary to me, but I could be mistaken. Please, post your views. Many thanks
