VO2 max intervals can be a valuable addition to a cyclist's training, but it's essential to understand their purpose and implementation. These high-intensity efforts aim to increase your body's ability to utilize oxygen, resulting in improved endurance and performance. While it's true that VO2 max intervals can be exhausting, they're not meant to be done excessively. In fact, research suggests that short, focused intervals (20-30 minutes, 2-3 times a week) can be more effective than prolonged, frequent sessions. It's also important to note that VO2 max intervals are most beneficial for experienced riders looking to optimize their performance. As a new cyclist, it's crucial to establish a solid foundation of endurance and build up to more intense training.
