In this educational fitness video, Eric Roberts explains that VO2 max—the maximum amount of oxygen the body can utilize during intense exercise—is the most reliable indicator of longevity, disease risk, and cardiovascular and pulmonary health. He outlines four practical strategies to raise VO2 max: (1) Zone 2 cardio performed at 60‑70% of maximum heart rate, (2) interval training such as 30 seconds of running followed by 90 seconds of walking repeated 5‑10 times, (3) strength training 2‑4 days per week with 5‑10 repetitions per set, and (4) maintaining a healthy body‑fat percentage. By following these methods, viewers can improve their aerobic capacity and overall health.
