Exercise induced anxeity

do you feel panicked or just those symptoms?

kinda like weight on your chest? you could be having some sort of anxiety attack, im no doctor. i know when i do some extra movement with my body it sometimes can cause an attack for me since my heart is beating fast and my chest feels heavy.

I sometimes feel anxious after a good workout myself. Are you taking any supplements? Like pre-workout or caffeine?

I used to be into bodybuilding and then powerlifting. I deal with chronic depression, fatigue, anxiety and back pain.

Weight training is a stimulus and can possibly add to the overstimulation from anxiety. I don't do workouts like I used to, but I'm able to do some. I've learned to never go to more than about two reps short of 'failure'. It took me a while to learn to back off. You can still improve from there. You can also add 'volume' (more sets basically), and do the sets with even a little less intensity of effort. Also, the heavier/lower reps you go, the more it affects your (or anyone's) CNS. I can't do high rep sets because they simply wear me out, but if I do 5-9 reps for most exercises, but again stopping short of all-out, it generally works OK.

Extra:
When I was powerlifting, if I did a really hard set of three reps for something bigger like squats, there were times when something would just go off in my CNS and I'd be what I call wired and tired for 2-3 days. It was awful. I didn't really realize what was going on at the time.
