B · Reasonable confidenceStrength training and the risk of serious disease and death
Subject: Muscle-strengthening activity and risk of serious conditions
What this means
People who did muscle-strengthening exercise had a 10 to 17 percent lower risk of death, cardiovascular disease, cancer and diabetes. The lowest risk was at around 30 to 60 minutes per week.

What does this rating mean?
A solid systematic review with caveats, or consistent indications with a limited scope.
Findings
Muscle-strengthening activity is associated with a lower risk of, and lower mortality from, various serious conditions.
Who this applies to
Adults aged 18 and over without severe health conditions.
What to keep in mind
These are associations, not proven cause and effect. Above about 60 minutes per week the benefit did not keep increasing, so whether more training adds anything is unclear.
Practical conclusion for REZA
REZA uses this as an argument to take strength training seriously, always with the limitation attached. A promise of disease prevention to an individual client would go further than this research allows.

Methodology
Systematic review with meta-analysis of cohort studies
Limitations
This is observational research. It shows association, not causation. People who do strength training may differ in other ways from those who don't.
