The type of cardio training that emphasizes short, intense bouts of exercise followed by periods of recovery is anaerobic interval training. This training method involves alternating high-intensity efforts with low-intensity recovery periods. It is effective because it allows for a significant cardiovascular challenge while also promoting improvements in muscular strength, speed, and power.

During anaerobic interval training, the body primarily relies on energy systems that do not require oxygen, allowing participants to push themselves hard for short durations, typically ranging from 20 seconds to a few minutes. This is contrasted with steady-state training, which involves maintaining a consistent intensity level over an extended period, and endurance training, which focuses on building stamina with lower intensity. Plyometric training, while intense, primarily focuses on explosive movements rather than the structured interval format that characterizes anaerobic interval training. This differentiates anaerobic interval training as a distinct and effective approach for enhancing overall fitness and aiding in weight loss.
