Which benefit is typically associated with increased lean body mass?

Increased lean body mass is closely linked to improved physical strength and fitness. Lean body mass, which includes muscle, bone, and organs, plays a significant role in the body's overall metabolism and functional capacity. By increasing lean body mass, individuals typically experience enhancements in muscle strength and endurance, which can lead to better performance in physical activities and improved overall fitness levels. This adaptation is beneficial for various types of training, whether for strength, endurance, or general fitness, ultimately resulting in more effective workouts and physical capabilities.

In contrast, options related to decreased metabolic rate, higher body fat percentage, and reduced cardiovascular endurance reflect outcomes that do not correlate positively with increased lean body mass, highlighting why they are not the correct choice. Enhanced lean body mass generally contributes to a higher metabolic rate, lower body fat percentage, and improved cardiovascular endurance, creating a more favorable fitness profile overall.
