Answer: A - Interval training involves exercise followed by a properly prescribed rest period.

Interval training is less demanding than the other types of aerobic training because of the rest period. It helps to increase the strength and power of a healthy person.

Continuous training involves sub-maximal energy which is sustained. This type of training improves endurance.

Circuit training involves a series of exercise activities. At the end of the last activity, the exercise is started from the beginning, and again the activities are done through a series of repeated exercise activities.

Circuit-interval training involves a combination of circuit and interval exercise activities.
