Some years back my buddy and me were doing bb good mornings, real light weight since it a part of a circuit ( man if I only knew how dumb we looked)
After the workout, my buddy proceeds to the shower butt neeked n all, suddenly his back locks up. I mean, the dude could not move. Needless to say embarrassing gym moment #1 x infinity. He ended up in the ER needing a cortisone shot.
Fast forward some years and I've always had a semi mental block when it came to direct lower back training. I do knee level rack deads with out issue, but I never used any weight on the 45degree hyper extension machine. Well this week I did. Worked up to a 35Lbs plate for a set of three. Soft back on the neg, flexed hard at the top for a 1s hold. The most insane pump in my lower back ever. It felt so weird I began to panic and didn't shower for 30 minutes to wait for it to subside. lol
Nothing felt "wrong" per say, but he sensation was so intense, Im not sure if that is what I'm supposed to feel.
Sorry if this is trolling post status, but I just wanted to know anyone else that have had a similar experience when they fist hit their erectors full on.
