When should ordinary intervals be used?

Ordinary intervals, especially in the context of exercise, should be used with consideration of several factors, such as individual goals, time constraints, and metabolic restoration. According to Martin Gibala, the optimal rest period between intervals can depend on metabolic factors such as phosphocreatine restoration. Practical considerations like the individual's goals and the time available for the workout should also be taken into account.

Martin Gibala emphasizes the importance of variability and adapting the intervals to ensure comprehensive bodily stress, which can drive better adaptations over time. For most individuals, there isn't a single best program, and varying the intervals can be a beneficial strategy.

In studies, a common protocol used for interval training is three times per week, which provides a structured yet flexible approach for most people 1.
