Or u could just tell your girlfriend that you let him win.. And avoid the embarrassment..

Lots of people here apparently don't know about the whole size to strength thing, where the smaller you are, the more effective your muscle mass is. There's a reason ants can lift 10 times their own weight easily and larger creatures can't.

I was thinking the same thing. The lil kid doesn't have to lift as much body mass/weight.

Do you even lift?

you gotta lift bro

well what did she say...

Kids have an abundance of energy. Pretty sure most kids could out do an adult in those circumstances unless said adult was in training at the gym alot.

I think someone fancies your girlfriend.

Haha! That sounds like something I'd do!

His dad (or other make role model) must be a lovely guy for the kid to be acting like that at 7. The kid can expect a few ass whoopings from his peers if he keeps that attitude up.
