I can't perform a single pull-up, or even a chin-up. I can't lift myself to the bar, however when using a low bar (one that I can start from the top) I can perform 3-4 chin-ups but still no pull-ups. What's the matter with me? How can I fix this?
Do slow negatives, start at the top and lower yourself slowly, this is the way most people get strong enough to do their first, clean pull/chin-ups. If you have a rubber band to attach to the bar, that can work too.,
