What defines interval training?

Interval training is defined by the practice of alternating between periods of high-intensity exercise and low-intensity exercise or rest. This method maximizes the benefits of cardiovascular and muscular endurance within workouts, allowing individuals to work at higher intensities for shorter durations compared to steady-state exercise.

The high-intensity segments enhance anaerobic and aerobic fitness, while the low-intensity intervals provide active recovery, helping to reduce fatigue and improve overall exercise performance. This approach not only boosts the metabolic rate but also encourages more calories to be burned even after the workout is completed.

In contrast, continuous low-intensity exercise typically engages the body at a steady pace without varying intensity, which does not provide the same cardiovascular and muscle conditioning benefits as interval training. Solely focusing on strength training limits the cardiovascular benefits that interval training would offer, while consistent moderate exercise for long durations usually lacks the varied intensity that characterizes interval training.
