Are girls stronger than they look?

I have a female friend who is short and quite healthy. She workout a little bit but appears weak. I once challenged her to an arm wrestling match and to my surprise, she was quite stronger than she looked and her biceps also bulged during the match which you canโ€™t see normally. She gave me a tough time and I was stunned that how can a girl who is so short and appears weak is destroying me. I was beaten again and again by her. Are girls really stronger than they look?
