You do not lose muscle because you get old. You get old faster because you lose muscle. Strength training is one of the most powerful tools we have to preserve independence, metabolic health, and longevity.

Aging isn’t what makes you weak. Being weak is what makes you age. Two of the most powerful forms of exercise for healthy aging are strength training and high-intensity interval training (HIIT). Both help your body build healthier mitochondria—the tiny power plants inside your cells that create the energy your brain, heart, and muscles need to function. And you don’t need a gym or an hour-long workout to benefit. Think of movement as “exercise snacks” throughout the day: • Stand up from a chair 10 times • Do wall push-ups • March quickly in place for 30–60 seconds • Walk fast enough that you can talk, but not sing Your starting point doesn’t matter. What matters is going from nothing to something—and gradually challenging your body as you get stronger. Thank you for having me on, CBS Mornings.

Most heart attacks today are not simply a cholesterol problem. Aside from a smaller group with inherited lipid disorders, many are connected to metabolic syndrome, prediabetes, and poor metabolic health. Too much sugar and starch can drive up insulin, triglycerides, and ApoB long before symptoms appear. The good news is that much of heart disease is preventable. Start with whole foods and limit ultra-processed foods. Combine aerobic exercise with strength training. Take a 10-minute walk after meals to help keep blood sugar under control. Prioritize sleep, manage stress, avoid smoking, and monitor your blood pressure. And do not assume that looking healthy means you know your risk. Go beyond the standard cholesterol panel. Ask your healthcare provider about ApoB, Lp(a), hemoglobin A1c, and fasting insulin. Check your blood pressure at home, track your waist-to-height ratio, and follow these numbers over time. Heart disease, high blood pressure, abnormal cholesterol, and insulin resistance are not separate problems. They are part of one interconnected biological system.
