I've just run face-first into a wall of my own construction.
I had my usual upper body day yesterday. I've mentioned before how I've been going light on pressing movements due to my shoulder (which has been getting better). I've been able, however, to go hard and heavy for pulling movements. Given that I've also been limited for lower body due to nagging knee injury, going heavy on pull movements (back, biceps) has kept lifting enjoyable.
Until yesterday.
It was tough while I was doing, and I had been light on sleep going in. By the time I went to bed, my left biceps--specifically, the brachialus--was hurting in an all-too-familiar way. I woke up this morning to it feeling a bit worse, and it seems like more than DOMS. Crap. I injured it a long time ago, and while it has occasionally flared back up, it's been good for the last few years.
So now my presses are limited, leg work is limited, and my pulls are compromised. I think I'm taking this week off and seeing how I feel. Maybe some yoga, hiking, and light jogging in the meantime.
Crap crap crap.
