Overview

  • Adults who maintain consistent physical activity across their lives have 30% to 40% lower all-cause mortality compared to inactive peers.
  • Initiating regular exercise at any point in adulthood reduces death risk by up to 25%.
  • Individuals who increase activity from below-recommended levels to at least 150–300 minutes per week see a 20% to 25% reduction in mortality risk.
  • Consistent exercisers see a 40% lower risk of heart disease death and a 25% lower cancer mortality compared with inactive adults.
  • Exceeding 300 weekly minutes of exercise provides minimal extra longevity benefit, and stopping activity erases previously gained risk reductions.
