What type of training is characterized by high intensity work followed by rest or lower intensity?

Interval training is characterized by periods of high-intensity work followed by rest or lower intensity. This training method alternates between bursts of intense exercise and recovery phases, allowing individuals to push their limits during the high-intensity segments while also incorporating recovery to sustain performance over longer durations.

This style of training is effective for improving both aerobic and anaerobic fitness levels, enhancing overall performance, and can be adapted to various types of exercises—making it versatile for different fitness goals. The emphasis on intensity in interval training promotes adaptations such as increased cardiovascular capacity, improved muscular endurance, and greater calorie burn, making it a popular choice for those looking to maximize performance in a shorter time frame.

In contrast, cardiovascular training typically focuses on maintaining a steady state of activity over an extended period, strength training primarily targets muscle building and strength without the same interval structure, and endurance training emphasizes prolonged activity at sub-maximal efforts, rather than alternating high and low intensities.
