What is a common disadvantage of interval training?

Interval training often involves repeated cycles of high-intensity exercise followed by periods of rest or lower-intensity activity. While this training method can be highly beneficial for improving cardiovascular fitness, speed, and stamina, one common disadvantage is that it may demotivate participants due to the repetitive nature of the workouts. The structured format, which typically includes repeating specific sets and intervals, can lead some individuals to feel bored or lose interest, especially if they are expecting variety in their workouts. This sense of monotony might discourage them from continuing with the training over time, highlighting the importance of incorporating variety or modifying workouts to maintain engagement and enthusiasm for the training regimen.
