To improve your VO2 Max, it is not necessary to run; you can choose any activity that elevates your heart rate for a long duration, provided that you maintain good movement mechanics, including low-intensity activities over prolonged periods.

This advice aligns solidly with the principles of exercise physiology. Scientific literature, notably through meta-analyses and systematic reviews (e.g., Milanović et al., Sports Medicine), confirms that improving VO2 Max does not depend on a specific mode (such as running), but on the engagement of the cardiovascular system and oxygen consumption. The idea that moderate intensity over a long duration (Zone 2) is effective is supported by studies on endurance training, which show an improvement in stroke volume and peripheral adaptations. The emphasis on "good mechanics" is a prudent and relevant recommendation for preventing injury, an element often neglected in high-intensity training. There is no exaggeration here: the post correctly popularizes the concept of metabolic specificity in relation to the choice of exercise. In short, the approach is scientifically robust and favors the sustainability of practice.
