As a followup to this question, can I get to 20 pull-ups (instead of push-ups), doing the same routine as in the ascepted answer? i.e. going for failure, with moderate speed repetitions, and resting half a minute between each serie.
Also, is it possible to get some muscle growth while doing that routine? I'm asking because I don't know if one can train to have muscular endurance while having muscular growth at the same time.
