Assume You Want Extra Cardio for a Wholesome Coronary heart? New Analysis Says This Is Sufficient (150 Minutes or 600?) 🫀
Prior to now, I’ve talked about researcher James O’Keefe (together with in this podcast episode), who has proven that the “Goldilocks zone” of train actually does not should be any greater than about 150 minutes of moderate-intensity cardio train or 75 minutes of vigorous train per week.
O’Keefe has additionally raised issues a few potential “hazard zone” with persistent vigorous train above 4 to 5 hours per week (roughly 240–300+ minutes of heart-pounding effort), particularly when sustained over a few years. In long-term endurance athletes, these excessive train volumes have been linked to issues like atrial fibrillation, myocardial fibrosis, and coronary artery calcification.
However a brand new British Journal of Sports activities Medication research discovered that the usual 150-minute-per-week guideline was related to solely modest cardiovascular safety, about an 8–9% decrease danger, whereas roughly 560–610 minutes per week of moderate-to-vigorous bodily exercise was related to greater than a 30% decrease danger.

So does this completely contradict what O’Keefe is saying? Not likely.
The brand new research checked out mixed moderate-to-vigorous bodily exercise, not vigorous train alone. Somebody might accumulate 600 minutes of train principally by strolling and different average exercise and by no means come near O’Keefe’s proposed ceiling for persistent vigorous train.
The research are additionally considerably totally different outcomes. The brand new research tracked cardiovascular occasions—together with atrial fibrillation, coronary heart assaults, coronary heart failure, and stroke—utilizing well being data. Nevertheless it didn’t immediately assess a number of the structural adjustments O’Keefe has raised issues about in high-volume endurance athletes.
My ultimate take? Do what has been proven to offer a strong baseline for health.
Get round 150 minutes per week of average cardio train (or 75 minutes of vigorous cardio train), and energy practice frequently. Then, accumulate a crapload of strolling and different low-to-moderate-intensity actions all through the day.
