Story at-a-glance
- A 2025 meta-analysis of 46,694 cancer patients found that higher muscle strength and cardiovascular fitness reduced all-cause mortality risk by 31% to 46% across different cancer types and stages
- The same study showed that each unit increase in muscle strength reduced death risk by 11%, while increases in cardiovascular fitness lowered cancer-specific mortality by 18%
- Beyond improving cancer outcomes, a 2021 review of 188 studies found that regular physical activity reduces the risk of developing multiple cancer types by 10% to 20% through various mechanisms
- For cancer patients, intense workouts aren't necessary; simple activities like daily walks or standing up from a chair multiple times meaningfully improve strength and fitness
- The optimal daily target for walking is 10,000 to 12,000 steps, while strength training is most effective at 40 to 60 minutes weekly, spread across two to three sessions; exceeding 130 minutes negates benefits
