These are exercises that involve two movements as a pair and are therefore often considered cardio supersets. All of these exercises offer different benefits, but they have essentially the same goal, to bring new life to your aerobic training.
Each combination of the two exercises has the potential for minimal transitions from one movement to the next, so you have little time to rest despite pre-determined periods.
Also, each of these workouts can be a kind of high-intensity interval training (HIIT). This way of training is extremely popular because it is challenging, it is often fun and it gives results without spending a lot of time on it.
