Progressive resistance training (which means continuously increasing weight training) is the most crucial tool for anti-aging. When muscles contract, they secrete so-called myokines into the brain and various organs throughout the body, coordinating the body's network to maintain a healthy and thriving state. "Progressive" means continuously increasing the load, so relying solely on bodyweight exercises, such as push-ups and pull-ups, is far from sufficient. It is still necessary to frequently work out in a gym with abundant equipment, preferably with a coach's guidance. Strength training can increase bone density, and its stimulating effects on certain areas of the brain are unmatched by simple activities like running or swimming. However, the public instinctively associates strength training with the rampant use of performance-enhancing drugs in the bodybuilding industry, completely unaware of the immediate preventive effects of progressive strength training on many chronic diseases. Older adults especially need progressive strength training to maintain flexible mobility. Just taking medication and supplements, and doing some walking or jogging, while hoping to combat aging, is not even close to the right approach.
