Which training type is most associated with increases in fat-free mass?

• A. Endurance training
• B. Resistance training
• C. Flexibility training
• D. No training changes

Answer: (B)

Gaining fat-free mass comes from building more tissue, especially skeletal muscle and bone. Resistance training provides the necessary mechanical overload that stimulates muscle protein synthesis and muscle fiber hypertrophy, so the muscles grow in size and strength. As the muscles enlarge, fat-free mass increases. It also promotes bone mineral density with a similar overloading stimulus, contributing to lean body tissue. Endurance training boosts aerobic capacity and mitochondrial networks, and it can lead to some lean tissue gains, but not to the same degree of muscle hypertrophy as resistance training. Flexibility work mainly improves tissue length and range of motion with little effect on muscle mass. No training changes would not drive any of these adaptations.
