This really happened, but I don't know if I could do it now.

When my husband was in Iraq, I was seriously in a bad way. Anyhow, after one of the particulary gruesome reports on a beheading, I was so enraged that I was pacing up a storm. My daughter handed me a cast iron poker from the fireplace and said, "here, take it out on this thing." Kinda like punching a pillow. To our amazement, I bent the thing into a U.

Very weird.

It is surely strange what the human body can do with the right (or wrong) emotional stimulas.
I's have seen a woman who barely stood 5 feet and no strength training what-so-ever tall flip a car (a heavy 1970's American vechicle) onto it's side because it almost ran over her children. She just ran up, put both hands underneath it's doors and lifted. Collasping it onto it's side.
Unfortunately, when she had calmed down and the drive had been subdued (he was drunk), she began to feel the effects of her effort and she had to be treated by a form of Chinese therputic massage (since the muscles needed to be forced to relax before they hemerage or the like). But, in the end, she laughed off the pain and said that she was going to join the gym. When she was last encountered -some years ago- she was an amateur powerlifter going for her first contest.
She told I the trick was to 'remember the feel that gave you the power and channel it properly'.
The same theory should work for you in your training, dear Alisa.
Best of luck -in all things.
Peace

this would be my first post, hooray...

The human body is capable of 5x the force a person may exert under normal conditions. The brain normally prevents this, but i believe hypnosis, rage, or other altered states of mind can shut down this block. The problem is that it can tear the muscles in question.

The_Pimp_NeonBlack is probably right though. Anger is not healthy, and you should relieve that stress. Exercise is great for removing tension.

And you might run out of pokers.

Speaking of pop culture insertions, that line was even used in revised version of Battlestar Galactica by the character Number Six when she pinned the shorter Baltar to a wall.
