So first day of calisthenics work out and first time properly trying HSPU. Did 3 sets of 8. Not all the way down, not quite that strong yet, but still did 'em as well as I could! Anyways, after my workout, I looked at my face and I've got popped blood vessels around the eyes!? What's up with that? I'm in good health, I've been inverted before! 3 years ago I did a play where the one scene I was in required me to hang up side down for 25 minutes, never saw this before. Any idea what's going on or why? Even better, how to make it not happen and make it go away? I really want to keep on this whole calisthenics gig when I'm away from the gym, and HSPU seem to really hit my shoulders nicely!
