How does resistance training affect metabolic rate?

Resistance training positively influences metabolic rate primarily by increasing lean body mass. When individuals engage in resistance training, they stimulate muscle hypertrophy, leading to a greater amount of muscle tissue. Since muscle is metabolically active tissue, it requires more energy to maintain compared to fat tissue, resulting in an increased resting metabolic rate. This means that even at rest, individuals with more muscle mass will burn more calories than those with less.

Additionally, this effect is beneficial not only for weight management but also for overall metabolic health, as a higher resting metabolic rate can support energy balance and fat loss efforts. This understanding underscores the importance of incorporating resistance training into fitness regimens for those looking to enhance their body's metabolism.
