Most people think of strength training as something for athletes, bodybuilders, or younger people chasing fitness goals. But on Morning Air, Dr. Brian Donahue shared a different perspective: muscle is about much more than appearance. It’s about health, longevity, and protecting the body God gave us.

Dr. Donahue explained that studies have found a strong connection between muscle strength and long-term health. In fact, even hand grip strength has been used as a predictor of overall wellness and longevity. Stronger muscles are linked to benefits for cardiovascular health, metabolism, and even reducing the risk of falls as we age.

Muscles also play an important role in supporting the joints. As we get older, muscle loss naturally occurs unless we actively work against it. “By 40 years old,” Dr. Donahue explained, “we start to atrophy,” often losing muscle mass year after year. That loss of strength can contribute to knee pain, hip issues, and instability.

Another surprising benefit of muscle is its role in regulating blood sugar. Dr. Donahue noted that muscles store much of the body’s glycogen, helping process sugar properly. Without enough muscle, excess sugar is more easily stored as fat instead.

The encouraging news? It’s never too late to start. Dr. Donahue emphasized that even people in their 70s and 80s benefit from resistance training. Starting slowly with proper form, lighter weights, or resistance bands can make a significant difference over time. “A body in motion stays in motion,” he reminded listeners.
