The usual advice to exercise a certain amount each week might not be the best for people with serious heart problems — they might need a different plan.
See the scientific wording
Current physical activity guidelines recommending 150–300 minutes per week of moderate activity or 75–150 minutes per week of vigorous activity may not be optimal for all individuals, particularly those with high or very high cardiovascular risk.
Correlational — new studies may shift this
ObservationalOne moderate-quality study links this claim to the outcome, but causation is not established.
What the research says
1 study reviewedSupporting (1)
Cohort StudyHuman
This study found that people with high heart disease risk don’t need as much intense exercise as healthy people to stay healthy — too much might even hurt them. So the usual exercise rules might not work for everyone.
Contradicting (0)
No contradicting studies found yet
That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.

How Fit Body Science checks a claim
- 1
We isolate the claim
Health advice from videos, articles and studies is broken down into single, testable claims.
- 2
We find the research
Each claim is matched against peer-reviewed studies, with every source cited by DOI.
- 3
We grade the evidence
Studies are scored on methodology, statistical rigor, transparency and publication quality.
The fitness and health internet is full of confident claims. We check them against real research.
Every claim on this site is traced back to peer-reviewed studies, scored on methodology and reporting quality, and given a verdict you can audit yourself — sources, DOIs and all.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review of Physical Activity Guidelines' Effectiveness in Reducing Cardiovascular Events Among High-Risk Populations
Includes only studies with high-risk cardiovascular populations, compares adherence to current guidelines vs. individualized activity regimens, and measures hard endpoints like myocardial infarction, stroke, and all-cause mortality over ≥2 years.
Randomized Trial of Individualized vs. Standard Physical Activity Guidelines in High Cardiovascular Risk Patients
Double-blind, parallel-group RCT enrolling adults with high or very high cardiovascular risk; randomized to follow standard guidelines (150–300 min moderate or 75–150 min vigorous) or individually tailored activity prescriptions; primary outcome: composite cardiovascular event rate over 3 years.
Prospective Cohort Study of Physical Activity Adherence and Cardiovascular Outcomes in High-Risk Individuals
Large prospective cohort of 10,000+ adults with documented high cardiovascular risk, tracked for 5+ years; activity levels measured via accelerometry; outcomes include hospitalization for CVD, mortality, and functional decline.
Case-Control Study of Physical Activity Patterns in High-Risk Patients with vs. without Cardiovascular Events
Cases: high-risk patients hospitalized for acute CVD event; Controls: matched high-risk patients without events; retrospective assessment of activity adherence to guidelines over prior 1–5 years using validated questionnaires.
Cross-Sectional Survey of Physical Activity Levels and Cardiovascular Risk Markers in High-Risk Adults
Single-timepoint survey of 5,000 adults with high cardiovascular risk; measures self-reported or device-based activity against biomarkers (e.g., LDL, hs-CRP, blood pressure, VO2 max); no follow-up.
