Having a client do 20 push-ups followed by 30 seconds of recovery is an example of what?

The scenario of having a client perform 20 push-ups followed by 30 seconds of recovery fits well into the concept of volume intervals. Volume intervals are characterized by completing a certain number of repetitions of an exercise, followed by a rest period before the next set or exercise. In this case, the specific number of push-ups (20) represents the volume of exercise, and the 30 seconds of recovery allows the client to recuperate before potentially repeating the set or moving on to another exercise.

This differs from other training methods. For instance, timed volume interval training emphasizes completing a task within a set time frame, which is not the focus here since the number of push-ups is predetermined rather than time-based. Tabata training specifically involves high-intensity intervals of work (typically 20 seconds of intense activity followed by 10 seconds of rest) for a total of 4 minutes, which does not align with the format of 20 push-ups followed by 30 seconds of recovery. Lastly, high knees is a specific exercise that does not apply to a set of push-ups followed by rest. Hence, the concept of volume intervals is most fitting for this scenario.
