I’m not sure what I’m exactly doing wrong, if anything, but the last two times I was in the gym, the back my head started hurting.
It felt like all of the blood was rushing through the back of my neck, and into my brain.
Just today, it happened within the first 30 seconds of me stepping into the gym. Just as I finished performing a second military press with an empty bar. (I got almost nothing done today.)
This also happened two days ago, just as I ended my session with a few sets of front squats.
What’s the most likely cause for this?
I’ve been getting sufficient rest, hydration (I think), food, etc.
