Set-point theory suggests that the body can only hold so much muscle due to genetics. Which statement best reflects this?

• A. Unlimited muscle mass is possible
• B. Genetic limit to muscle mass exists
• C. Diet alone determines muscle mass
• D. Hormonal changes do not affect muscle

Answer: (B)

Set-point theory describes a range of muscle mass that the body tends to maintain, with genetics largely setting that ceiling. Because of this, there is a genetic limit to how much muscle can be gained and sustained, even with proper training and adequate nutrition. You can approach that limit through progressive overload and sufficient protein and calories, but you won’t keep gaining indefinitely beyond the genetic cap. This is why the statement about a genetic limit to muscle mass best reflects the idea. The other options contradict the genetic influence, overlook the role of training and nutrition, or misstate the impact of hormones on muscle growth.
