Certified Personal Trainer (NSCA) Practice Exam 2025 – Complete Prep Guide

Strength training positively influences resting metabolic rate (RMR) primarily through the increase in muscle mass it facilitates. Muscle tissue is metabolically active, meaning it requires more energy to maintain than fat tissue. By engaging in strength training, an individual can increase their muscle mass, which in turn raises their RMR. This elevation means that the body burns more calories at rest, even when not engaging in physical activity.

The increase in muscle mass doesn't just lead to more calories burned during exercise but also enhances calorie expenditure throughout the day. Thus, individuals who incorporate strength training into their fitness routines can experience an overall boost in metabolic efficiency, contributing to weight management and overall health.

This understanding highlights the importance of strength training not only for building strength and endurance but also for its significant role in metabolic health and weight management strategies.
