Did you ever lift/workout with a sibling?

I sometimes do Cardio and run with my sister.

Once I went to the weight room with my brother and it was a bit intimidating to say the least.
I dumbell benched the 10 lb dumbells and then he asked me for a spot while benching the 95 lb dumbells.

I weigh 95 lbs :S
