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?

  • anatomy -

    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.
