the warm-up nobody talks about

Right so everyone bangs on about dynamic stretching and leg swings before training, which fine, yes, do that. But the thing that actually changed my sessions was spending like 3-4 minutes just hanging. Dead hang from the bar, passive, doing nothing. Shoulders decompress, lats wake up, grip activates without you even trying. I started doing this before any upper body work and honestly the difference in how my first pull-up feels is kind of annoying — as in, why did I not do this years ago. Mind you I was also rushing warm-ups for years so that's on me.
