It’s easy to assume that, since weightlifters aim to build strength and muscle, they have a greater need for protein than endurance athletes. This is one of those questions that’s best answered on a case-by-case basis. On one hand, endurance athletes who train heavy for hours on end may require more protein simply because their energy needs are so high. This would be especially true if they are keen on losing fat. On the other hand, competitive lifters like people in strongman competitions need extraordinary amount of calories and protein.
