More movement helps hearts — especially if you're at high risk

Surprising Findings
The benefit of MVPA was strongest in the very high-risk group (HR 0.80), yet the abstract does not specify an optimal dose—contradicting claims in the key claims section that 42 min/day or week is optimal.
Common belief is that more exercise always equals more benefit—but this study implies the relationship may be nuanced by risk level, even if exact thresholds aren’t stated.
Practical Takeaways
If you're at high risk for heart disease, focus on replacing sitting time with brisk walking or light exercise—even small increases may offer outsized benefits.

If you exercise hard for more than 42 minutes every day, you’re less likely to have heart problems later on.
People who move more—especially those who do brisk walking, running, or other intense activities—tend to have fewer heart problems, and this benefit is even stronger for people who are already at high risk for heart disease.
If you're at high risk for heart problems, doing more than an hour of intense exercise a week might not help your heart as much as doing less — it could even be less beneficial.
If you're at very high risk for heart problems, doing just 42 minutes of intense exercise a week seems to give you the best heart health boost — doing more might not help as much and could even reduce the benefits.
If you swap some of your sitting time for activities like brisk walking or jogging, you might give your heart a bigger boost—especially if you're already at higher risk for heart problems.
