Resistance training increases lean body mass and decreases body fat. Which option correctly describes this effect?

• A. Increases LBM and increases fat
• B. Increases LBM and decreases fat
• C. Decreases LBM and increases fat
• D. Decreases LBM and decreases fat

Answer: (B)

Resistance training builds muscle and changes body composition by increasing muscle protein synthesis, which raises lean body mass, while also boosting energy use and improving the way the body handles calories. This combination tends to reduce fat mass, especially when paired with proper nutrition. So the typical and best-described outcome is gaining lean body tissue and losing fat, not the opposite. The other options imply fat gain or muscle loss, which don’t align with how resistance training generally shifts body composition.
