From looksmaxxing and sleepmaxxing to frictionmaxxing: 2026 has been a year of optimising specific aspects of life. The latest to emerge is VO2maxxing, which relates to how much oxygen your body consumes while exercising (V stands for volume, O2 stands for oxygen and maxxing means, well, maximising).
It’s based on the concept of VO2 max, which has been a concern for endurance athletes for years. This is measured as millilitres of oxygen consumed per kilogram of body weight per minute of exercise. The higher the VO2 max, the more effectively your heart and lungs are supplying blood to your muscles and, in turn, the more efficiently your muscles are extracting and using the oxygen from your blood. A high VO2 max is a good indicator of high fitness level, so it’s little wonder VO2maxxing is gaining traction.
