Did mat pulls off 7 mats for only 5 a couple days ago. I'd forgotten to take breaks at work and my back was feeling very stiff. Also, while doing kettlebell goblet squats I discovered that that's what's been bugging my shoulder. The fix for that is easy, just do high rep bar squats.
Up to 355 x 1
Shoulder hurt but singles were manageable.
250 x 10, 9, 8, 8
Pain here too but I'm stupid so I kept going.
90 x 8, 8, 8
Might do more after work, depending on if I get called in early for tomorrow.
