Swap your 10,000-step goal for just 10 minutes of vigorous exercise each day For most, "vigorous" means hitting roughly 80% or more of your max heart rate Both approaches are valuable, but intense exercise delivers bigger benefits per minute, and science agrees For example, new research shows that doing just 10 bodyweight squats every 45 minutes throughout an 8.5-hour sitting period improved blood sugar control more effectively than a 30-minute walk. These short, intense bursts—known as "exercis

Vigorous exercise delivers cardiovascular protection that light or moderate activity simply can’t touch The faster blood flow generated during vigorous exercise creates high shear stress on artery walls (a good stress that triggers powerful endothelial adaptations) This stress boosts nitric oxide and prostacyclin, improving vascular function Repeated over time, this makes arteries more flexible, more resilient, and more resistant to atherosclerosis The science is clear Cardiovascular health is b
