Woke up with horrible wrist pain today. Left one. Its killing me! It's a little better now. Hopefully it doesnt stop me from benching later today. I think I slept with my hand in a weird position maybe.
Also, god damn my hip flexors are veryyyy uncomfortable. After those 315x10 squats, for the first time in my life i felt hip flexor pain after squatting. Always wondered how it happens to people and now I have it.
Did some research. It's caused by overactive hamstrings. When you squat and your hammies take over the glutes, it shifts your femur bone (i think thats the one) slightly out of alignment and makes it grind up against the hip socket. So the discomfort is actually in the hip socket cartilage itself, but since the hip flexor crosses over it, it feels like its in the hip flexors.
What everybody else does: stretch hip flexors.
What the actual solution is: foam roll hammies, activate glutes.
Edit: on second thought, stretching the hip flexors can help activate the glutes. antagonist inhibition.
