Q: Do older people need to lift weights? A: Yes, resistance training is ESSENTIAL for everyone as we age. We start to lose muscle mass regularly in our 30s, and if we don’t work to build muscle, we can become frail and weak as we age. Q: Does muscle really weigh more than fat? A: No. But muscle is denser than fat and takes up 22% less space in our bodies, so our clothes fit better! Q: I’m over 50 and my weight is fine. Why should I work out regularly? A: Working out is important for many reasons, including improved strength, endurance, and flexibility, which improves our quality of life.
