Professor Mark Peterson, of the University of Michigan Institute for Healthcare Policy & Innovation and Michigan Center on the Demography of Aging said, "Current research has demonstrated that resistance training is a powerful care model to combat loss of muscle strength and mass in the aging population…"
A July 2019 position statement by Quest Diagnostics said that "…resistance training can positively affect physical functioning, mobility, independence, chronic disease management, psychological wellbeing, quality of life and healthy life expectancy … in most cases, the vast benefits of resistance training largely outweigh the risks when training is properly implemented…"
Resistance training (or strength training) is, “Strength training is a type of physical exercise specializing in the use of resistance to induce muscular contraction which builds the strength, anaerobic endurance, and size of skeletal muscles … Recommended training for older adults is three times a week of light strength training exercises. Exercise machines are a commonly used equipment in a gym setting, including treadmills with exercises such as walking or light jogging. Home-based exercises should usually consist of body weight or elastic band exercises that maintain a low level of impact on the muscles. Weights can also be used by older adults if they maintain a lighter weight load with an average amount of repetitions (10–12 reps) with suitable supervision.”
