Strength training after 60: The surprising, lasting benefits

By Ken Berger

As we age, maintaining strength and mobility becomes increasingly important for independent living and overall quality of life.

While many seniors focus solely on low-impact cardio, a growing body of research shows that lifting weights should be prioritized after 60.

A groundbreaking new study revealed that one year of heavy strength training in your mid-60s can have profound, long-lasting effects on preserving leg strength and function for years to come.

Researchers at the University of Copenhagen recruited 451 men and women at retirement age to participate in a four-year exercise study. They were divided into three groups:

1) A heavy weight-lifting group that did full-body strength training 3x/week for one year, lifting 70-85% of their one-rep max.

2) A moderate exercise group using lighter resistance bands/bodyweight for one year, lifting about 50-60% of their one-rep max.

3) A control group that remained sedentary.

The results after four years were striking. While all groups experienced some age-related muscle loss, only the heavy lifting group maintained their baseline levels of leg strength and muscle function. The moderate exercise and non-exercise groups saw significant declines in leg strength over the four years.

You may be wondering: Why put so much emphasis on leg strength, specifically? Because it is a critical indicator of overall mobility, independence and reduced risk of falls and frailty as we get older.

Strong leg muscles are crucial for everyday tasks like getting up from chairs, going up stairs, walking for extended periods and maintaining balance. Preserving it allows you to stay active and self-sufficient well into your golden years.

"Leg strength is really important," Mads Bloch-Ibenfeldt, a medical researcher at the University of Copenhagen who co-wrote the study, told the Washington Post. "We use the legs in a lot of everyday tasks, like getting up and down from a chair. So it's important for reducing the risk of falls, and for a lot of everyday tasks we do."

Interestingly, the heavy lifting group maintained their leg strength levels despite also experiencing age-related muscle loss, similar to the other groups. This suggests the neuromuscular benefits of strength training go beyond just building muscle mass.

Weight training improves the neural connections between your muscles and your brain, increasing strength and coordination. It enhances your body's ability to effectively recruit and utilize the muscle fibers you have. This "neural adaptation" is why heavy lifting continues providing functional strength benefits as you age, even if you lose some muscle mass.

Based on this research, seniors should prioritize heavy strength training as a key part of their exercise routines. While activities like walking, swimming and cycling are excellent for cardiovascular health, they don't provide the same muscle-preserving, functional strength benefits as lifting weights.

The good news is, you don't have to be a bodybuilder or join an intense group fitness class. Following a basic full-body strength program 2-3 times per week, using weights challenging enough to reach muscle fatigue after 10-15 reps, is all you need.

Retirement is also the perfect opportunity to finally prioritize strength training. With more free time, you can visit the gym during off-peak hours and find a trainer who is experienced at working with people in your age group.

Aging inevitably brings some level of muscle and strength loss. However, by incorporating heavy strength training -- even just for one year in your mid-60s -- can pay off for years when it comes to preserving functional leg strength and mobility.

Combined with a balanced routine including aerobic activity and proper nutrition, strength training can help you stay active, independent and enjoying life to the fullest.
