I was looking at some door frame pull up bars yesterday. Now I was standing in my door frame and tried to imagine at which height the bar would be and it seemed a bit low (although I am a bit smaller than average).
What is the recommended height for a pull up bar? Should my arms be slightly bent when standing, should they be straight? Should I be freely hanging (eg jump up to reach the bar)?
I know that I could bent my knees when the bar is too low, but I'd like to know if there is something like a guideline, a montage recommendation or even something like a standard.
