Hi!
I have heard that different things can happen to people during deadlifts. I was doing some sets of deadlifts, and I ended up with a metallic taste in my mouth. Not sure how to describe it, kind of coppery.
Uh I’m not sure if that’s ever going to happen again in my life, but have you heard of that happening to anyone, and might be an indicator of anything, other than “oh wow those deadlifts were intense and I had a individual response to the intensity.”
