Bodyweight Calistenics vs Weightlifting

[Hendricks433]

guys at the rock clicking gym I go to, to warm up do the easiest bouldering routes and pull up with one arm to the next one then one armed to the next one and slowly climb up with no feet then back down, I have no idea how they do this, but it is my goal to do it one day.

I think you have to be a little feller to begin with to do those one arm pull ups. I am too big.
