One of the sad facts of life is that I've never really been able to do pull-ups. I think I've maybe squeezed one out a handful of times in my life, and they were probably pathetic in form, i.e., took some squirming to get my chin up there. Although I've never been particularly muscular---I've always been a much more of a cardio than a weight room guy, my biceps have always been weaker than my triceps, and my legs have always been stronger than my arms. While I'm not looking to be especially bulked up, it would be a huge victory for me if I could get to the point where I could do pull-ups, like, at least five in a row. However, what is the best training program to be able to do this? I don't belong to a gym, and don't plan to. I'm already doing hammer curls with dumbbells. What exercises should I be doing to build up enough strength to be able to get there? BTW, I don't have a pull-up bar yet. Once I would be close to being able to do them, I will install one. Then I could do pull-ups as a way to being able to do more. But I wouldn't see much point having one now, only able to wrap my hands around the bar and dangle there. Thanks.
