Visualization can be an important part of doing an exercise right. I recently came upon a bit of advice on another website and I could immediately feel an improvement in my form (despite having done probably thousands of pullups before). My question is: do you know any good visualizations for doing pullups?
For the record, the sentence which inspired this: During this initial movement, pretend that you are squeezing a pencil between your shoulder blades and do not let the pencil drop during any phase of the pull-up.
