That last set of 290 fucked my shoulder up again. Stupid me for not terminating the instant I felt pain.
Luckily, it's not serious, but any sudden motion causes a jolt of pain, just enough to let me know I need to change things.
Straight sets of 5 are too much. I have two options:
2. My current program, which kicks ass, but going back to unilateral training.
Taking an indefinite break from boxing until I feel prime again.
