Scientific Duration Guidelines by Health Organizations

Major health and fitness organizations provide these evidence-based exercise duration recommendations:

  • American College of Sports Medicine (ACSM): 150-300 minutes of moderate-intensity or 75-150 minutes of vigorous-intensity aerobic exercise weekly, plus 2-3 strength training sessions of 30-60 minutes.
  • World Health Organization (WHO): 150-300 minutes of moderate-intensity or 75-150 minutes of vigorous-intensity physical activity weekly, with muscle-strengthening activities at least twice weekly.
  • American Heart Association (AHA): Minimum of 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity weekly, ideally spread throughout the week.
  • National Strength and Conditioning Association (NSCA): Resistance training sessions of 30-60 minutes, 2-3 times weekly for general fitness, with higher frequencies for advanced goals.

These guidelines serve as foundational frameworks, but optimal durations should be personalized based on individual factors, goals, and preferences as calculated by this tool.
