The recommended exercise intensity level of 85% to 95% of VO2 max aligns with the understanding of optimal training zones for improving cardiovascular fitness and performance. Exercising within this range is considered vigorous intensity, which is effective for enhancing maximal aerobic capacity, increasing endurance, and promoting overall cardiovascular health.

Training at this level allows individuals to push their physical limits while still being able to benefit from adaptations such as increased stroke volume, improved oxygen uptake, and better muscle efficiency. For athletes and those looking to improve performance, this intensity level can facilitate significant gains in endurance and power when appropriately integrated into a training regimen.

In contrast, lower intensity levels, such as those in the range of 50% to 60% of VO2 max, might be more suitable for beginners or those focusing on recovery and building a base foundation of fitness. While higher intensities could lead to better results for experienced athletes, the balance of intensity and duration is crucial to avoid overtraining and injury. Thus, for those aiming for advanced performance improvements, the higher recommended range of 85% to 95% is the most supportive of serious conditioning goals.
