Not sure how accurate it was or how well I remember it but I once read an article that explained that your higher dexterity hand/limb(s) requires more conscious effort to reach the the same level of muscle utilization as a side effect of more sensitive nerve endings used for dexterity. And further speculated that the higher dexterity limb worked the muscles slightly more efficiently which can lead to slightly more muscle development in the non-dominate limb to balance out overutilization/less-efficient non-dominant limb. Suppose to be true for both arms and legs. However they did note that it only takes a small workout bias between limbs to surpass the small possibly natural differences in limb strengths.
