The Claim
In individuals with very high predicted cardiovascular risk, 42 minutes per week of vigorous physical activity is associated with optimal cardiovascular benefit, and engaging in more than this amount may result in a decline in cardiovascular benefits.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.

1 studyThis study found that for people at very high risk of heart disease, doing just 42 minutes of intense exercise per week gives the best heart protection — doing more doesn’t help as much. This matches exactly what the claim says.
