Phase 2 of cardiorespiratory training is primarily focused on aerobic-efficiency training. This stage is designed to build upon the foundation established in the initial phase, enhancing the body’s ability to perform aerobic activities more efficiently. During this phase, the training intensity increases with a focus on improving aerobic capacity, stamina, and overall endurance.

In this phase, the individual typically engages in longer-duration workouts at a moderate intensity, which helps in strengthening the cardiovascular system and improving the muscles’ ability to utilize oxygen effectively. The training is structured to challenge the body further while still remaining within an aerobic zone, promoting sustained energy release and building aerobic endurance.

This approach is crucial for individuals looking to enhance their fitness for longer physical activities, such as distance running or cycling, and is characterized by steady-state exercise rather than high-intensity intervals typical of other training phases.
