SUMMARY
Larger muscles can lift more weight due to their ability to generate greater force, as established by the work-energy principle. The equation W = Fd illustrates that work (W) is the product of force (F) and distance (d), meaning a larger muscle can apply more force to perform the same amount of work. While the energy required to lift a specific mass remains constant, the mechanical advantage provided by muscle size allows for increased lifting capacity. Additionally, factors such as bone length can influence lifting efficiency but are distinct from muscle size.
