Someone at the gym asked me to spot them and I told them I couldn't do that because I couldn't lift. He gave me a weird look and said rudely and was being sarcastic: "THANKS ALOT FOR YOUR COURAGE!"

Was I rude to refuse to spot him? I just didn't know how to spot someone and I couldn't lift anything heavy since it was my first time at the gym working out.

Yes

I spot my brother and he does 3 plates and other crap and I'm his sister and my max is only 100 soo I think you can spot cause it's not as bad as you think. You could of spotted

No I think you shouldn't spot to others

He was being a butthole, and you were right. Once you've built yourself up, beat his azz haha =)

You don't have to be able to lift the full weight to spot someone.

nah you did the right thing. You shouldn't spot someone if you aren't able to at least lift it up a little bit. Don't worry. The guy was just being a jerk.

Since this only happened in your imagination you have nothing to worry about, Sean.
