If I really had to blame one exercise, I'd be lying, but I'd say Heavy Flat BB Bench Pressing contributed the most.
It didn't happen at once per say, like dropping the bar on your chest or something similar to that. It was more pushing myself harder than I should have and letting my form slip because of stubborness and refusing to lower the weight. After my initial strength loss on my cut, I did a recomp and forced myself to lift the same weight. Got a niggle or two in my connective tissue, didn't stop, in fact I upped my frequency of training. At one point I was training chest heavy twice a day and doing push ups the following day - which is fine, but not when you let your form falter and you're injured.
It's like having a bruise on your arm and instead of letting it heal you keep hitting that spot.
I eventually got all kinds of pain in my left arm, which in my stubborness I refused to let heal or even care about it, well my body forced me to stop when my elbow, tricep and wrist went 'nope'.
So... I guess that techinically makes it an overuse injury? Lol.
But yeah, as it stands I have loss of sensation in my left hand at times and I can't even do missionary position without a sharp pain shooting in the wrist (too much info?).
As it stands the only exercises I can do are;
no benching at all, not even the bar, in fact just bending my wrist in that position for benching, overhand, suicide grip or any other alteration still hurts.
only hammer curls atm, most supination of the wrist hurts like hell
I can do very very light Incline DB Bench. Sadly I was pushing 35's before I hurt myself and I really loved that.
Maybe I can do back, have not tried since.
I can't do tricep extentions properly, the curling motion of the handle hurts.
Eh, wall of text, gonna stop here before this becomes a social media post.
