Homework Help: anatomy

if you wanted to flex your arm, and both your biceps and triceps contracted simultaneously, what would happen?

and where is most of the muscle weight found in humans?

If both contracted at the same time, there would be no movement. Since they are antagonistic muscles, one would counteract the other.

I would expect most of the muscle weight to be in the legs.

I hope this helps. Thanks for asking.
