Want to know why HIIT and sprint intervals can improve health beyond fat loss, especially for women in perimenopause? This clip explores how high intensity interval training and sprint interval training impact insulin resistance, blood pressure, and blood lipids by improving glucose uptake (via GLUT4 translocation), increasing vascular shear stress to drive VEGF, and supporting endothelial function with less reliance on estrogen. I also explain how muscle released myokines signal the liver to handle free fatty acids differently, helping shift cholesterol markers. We finish with why short, sharp sprint work can help reset circadian rhythm and why that matters for shift workers and metabolic health.
