Nearly 40% of Americans (38.5% to be precise) will be diagnosed with cancer of any site at some point during their lifetime, based on 2012-2014 data. Would you like to reduce your risk for cancer-related death by 31%? Engage regularly in aerobic and strength building exercise. Evidence, please! A study of 80,000 people found that people who did strength-based exercise had a 23 percent reduction in the risk of premature death by any means, and a 31 percent reduction in cancer-related death.((Emmanuel Stamatakis.
