Endurance sports were long considered the gold standard for health. However, more and more data show that strength training is also linked to a longer, healthier life. How much is beneficial—and what does the research really say?
What the Data Shows
Large observational studies have found that people who regularly train their muscles are, on average, less likely to experience early illness or death. It's important to note: these are correlations, not proof of cause and effect—because those who exercise often lead healthier lives in other ways too. However, a beneficial "dose" appears to be around 30 to 60 minutes of strength training per week; significantly more does not automatically yield greater benefits.
The combination of strength and endurance training performs particularly well. Some analyses report significantly lower mortality rates here—however, these high values apply to very high levels of endurance activity and not solely due to strength training.
Why Muscles Are So Important
Muscles are much more than just aesthetics. They support joints, stabilize the back, keep metabolism active, and protect against falls and bone loss in old age. From about the age of 30, the body slowly loses muscle without training—strength training directly counteracts this.
How to Get Started
- Twice a week is sufficient for beginners—with rest days in between.
- Train the large muscle groups: legs, back, chest, core.
- Possible even without a gym: squats, push-ups, exercises with your own body weight or resistance bands.
- Better clean and slow than heavy and wrong—technique over weight.
Even small, regular sessions make a big difference over the years—in line with the principle of moderation.
