If not having big biceps is the reason for her to say no to a date then move on. No big loss there.

Is there a gym where people can go to work on their tact? No? There should be. Dodged a bullet on that one though... Shallow people will nitpick you to the point where you actually believe there's something wrong with yourself. You're good. Screw her.

Sounds like a bit of a prick, but she also was saying that she didnt find you attractive. so im split 50/50

Well you're going to the gym for a reason...I'm sure the bigger biceps will come with time. A better personality for her probably will never come.

Her loss, OP Her true colors shine brighter than a unicorn's shit. At least you found out now, rather than later in your (potentially) committed relationship.

Sorry things didn't workout.

What a tactless way to speak. Sorry op.

I completely understand if she didn't find you attractive, but there's no need to be rude. You can always work on your biceps, but even then you don't have to modify your body to impress anyone but yourself. You'll find the girl that will see past that type of things. (:

As she walked away, you shoulda said, "Maybe so, but you've never seen a tumor bigger than my penis!" When all is lost, a Hail Mary like that just might work!

Just as a general rule women tend to go to the gym to work out, not be hit on. While she definitely could have been nicer about it I wouldn't suggest leaving the flirting for somewhere else unless you're very sure there's reciprocal interest.
