Answer

One's strength scales as the cross-sectional area of one's arms and legs, but one's weight scales with the volume of the body. As discussed on pages 236-237, the ratio of strength to weight is greater for smaller creatures. For comparable effort, a smaller gymnast will be able to lift a larger fraction of his/her own weight as compared to a larger gymnast.
