I lift heavy and don’t have too many issues with this. I also do a lot of stretching before I play, like a whole upper body stretch. I stretch lats, traps, biceps, forearms. I even try separating each pair of fingers as far as they’ll go to get wider stretches easier. The most essential, by far, is straightening your arm and pulling all your fingers back to stretch the bottom of you forearm and then pull them forward to stretch the top. I notice instant improvements in my playing when I do this. Its like your fingers are just getting the signals from your brain better or respond better to them or something. I’m no scientist or anything, but it works.
