Does anybody even know how to actually work the TVA other than this stupid pose? It seems nobody on the internet is able to figure out how to get it working. I have scoliosis or something and the TVA on one side is weak so I can tell if an exercise is actually working it. So far, out of all the exercises I do, probably tricep pushdowns work it the most. I feel it a little on bench press and OHP but not much. Most ab exercises don't seem to work it at all.
