What is the recommended frequency for strength training per week for most adults?

The recommended frequency for strength training for most adults is 2 to 3 days per week. This range is supported by various health organizations and guidelines, including the American College of Sports Medicine and the World Health Organization. Engaging in strength training within this frequency allows individuals to effectively build and maintain muscle mass, improve metabolic health, and enhance overall physical function.

Training two to three times per week is sufficient to promote muscle hypertrophy and strength gains while allowing adequate recovery time for muscles to repair. This approach helps prevent overtraining and reduces the risk of injury, which can be more common with higher frequencies of strength training. Furthermore, when coupled with rest days, this frequency provides a balanced workout routine that can be integrated into an overall fitness program.

Options suggesting lower frequencies, such as 1 to 2 days per week, may not provide enough stimulus for significant strength improvements, while options recommending more frequent training, like 4 to 5 days per week, could be excessive for many adults, especially those new to strength training or those with existing health concerns. Daily strength training might not allow sufficient time for recovery, which is crucial for muscle growth and repair.
