Is it normal that i lift weights when angry

It's not just normal, it's healthy! The adrenaline from the anger gets put to a more productive use. It'll probably keep your stress and anger in check and it'll help you sleep better too. Keep it up!

One time a girl betrayed me, that i liked and she "liked" me, and i was so mad i was physically shaking. The only thing that helped was benching heavy weight.

Great way to release some steam. Very productive. :)

if you have a little brother i like bench pressing my little brothers cause they think its fun and i might as well cause at least its working and 2 ppl benefit from it.

perfectly normal i workout when i'm angry 100's of pull ups and push up and ocationally bench pressing the old 250 pound weight

im a body builder myself and i feel i have an addiction to body building i like to boost my ego when i arm wrestle my family and kids at school i just cant beat my dad even when i lift my elbows up and use both my arms and my head lol my head i push with my forehead lol.

That's awesome! I find I workout so much better when angry, lol. Some bitch really pissed me off at Subway today when she did not hold the door for me. So, to blow off steam, I went for a long fast walk. I felt sooo much better after! :)

good for you, its a good release of energy and its awesome you channel it to something that helps you and keeps you fit, instead of punching walls or starting fights

Completely normal. When something has me riled up, I run it off. Nothing to clear the mind like a nice run and a hot shower.
