We break down the study findings and note that body composition, especially body fat percentage, and overall physical activity appear to be more important predictors of longevity than chasing VO2 max directly.We also compare VO2 max with other fitness metrics and say that focusing on one number can make people miss the habits that create it. We then shift to goal setting and explain that performance goals like improving a mile time or a back squat are often more motivating than aiming only at fat loss or a scale target. We finish with updates on the app, including testing on Apple and Android, and mention our upcoming appearance at Home Gym Con. We also note that athletes are already using the app and giving feedback.
