There is some math to the principle that the smaller the animal, the higher the weight it can move in proportion to its body size:
Assuming a small muscle has the same shape as a large muscle, the mass is in proportion to the cube (3rd power) of its length. But, its strength is in proportion to the cross sectional area, which is in proportion to the square (2nd power) of its length.
