Bit of a run down, 29, been lifting regularly for several years now. Currently running Cube and have been for over a year. Some days during squats the area where the rhomboid/lat connect tightens up pretty badly, not quite a cramp but irritating. Afterwards it feels like the muscle has been pulled. Have had it before but it was quite rare, and now it is becoming more common. The only change to my routine/form has been going barefoot and that as a whole feels much better. Dont see that could be the culprit anyway as I had experienced this (rarely) before while using my oly shoes. Anyone had experience with this before or know of some further specific stretches/warm ups I could try to remedy it? Thanks in advance.
