At a minimum, how many times should one strength train per week to boost metabolism?

Strength training 2-3 times per week is generally recommended to effectively boost metabolism. This frequency allows for sufficient stimulation of muscle growth and adaptation, which are key to enhancing metabolic rate. Engaging in strength training exercises stimulates muscle fibers to grow, and this increase in muscle mass can lead to a higher resting metabolic rate.

Additionally, training within this range accommodates recovery time, which is essential for muscle repair and growth. Overtraining without adequate recovery can lead to fatigue and injuries, effectively negating the benefits of the exercise regimen. Therefore, 2-3 sessions per week strike a good balance, promoting both the physiological adaptations necessary for an increased metabolic rate and the recovery needed for optimal performance.
