this is often the part where he's patched the most meaning he probably sources A LOT of strength from his back
which, combined with his core strength, allows him to pull off moves like these seemingly effortlessly
another look at them in motion maybe?
also, not his famous dimples of venus, but back dimples anyway (dimples of venus are lower, as explained in this thread https://twitter.com/graphicfighter/status/1143154554390949888)
I hope you enjoyed this vaguely informational thread and don't forget Jimin is a work of art because he crafted himself for years. This sculpted body didn't happen by magic.
Actually I can't decide if the "shoulder accidents" are really accidents when his sloppy shoulder line is partly the by-product of a bulgy trapezius... so let's say gravity does the rest.
tbh he be like "muscle pig" about jk but look who's talking he's a tight bundle of muscles himself
