I am suffering from the same problem and am currently trying to figure out whether I misunderstand pressure concepts or whether I am not able to apply them correctly.
Esp. when it comes to pressure in the arms during downswing, the muscle build tension which itself keeps my wrist join far too fix. IOW, it is prevented from moving and turning naturally, from “exploiting gravity” and so on. This is a sound problem. How can I build pressure and strength without tension?
Would be very glad to get help from the Tathata team as much as you probably.
