A recent study in Cell Metabolism highlights how two types of sport, high intensity endurance, and strength (resistance) training, improve cell functions and enable DNA code to retain its integrity over time. This supports the idea of doing cardio exercises, and complement them with resistance: push-ups, planks, lifting weights, etc. Doing one or the other is good. Doing both is best.
The New York Times interviewed the researchers and noted in their article: “The gains in muscle mass and strength were greater for those who exercised only with weights, while interval training had the strongest influence on endurance.”
Many centenarians do a combination of both, as documented in The Okinawa Program, in Robustness with Robert Marchand and Felix Martin‘s lifestyles, and in Junko Takahashi’s interviews of centenarians in Japan. Real life validates these findings.
