Which type of exercise program involves a series of exercises interspersed with rest periods? a
circuit training

b
interval training

c
calisthenics training

d
weight training

B) interval training

Explanation:

Interval training is a type of training in which the period of intense activity alternates with the period of active recovery. The duration and intensity of the work interval together with the duration and intensity of the recovery interval make up one series.

When planning interval training, it is necessary to determine: 1. the duration and intensity of the working interval, 2. the duration and intensity of the recovery interval, and 3. the total number of series.

Precisely because of the larger number of variables and the unlimited possibility of combinations, interval training is more efficient and interesting than continuous training.
