Circuit training is a mix of strength training and endurance training. In a circuit-training workout you do a group, or circuit, of exercises with little or no rest between exercises. Usually, one circuit consists of 4 to 10 exercises. Each exercise is done for a set number of repetitions or period of time before you move to the next exercise. For example, you might do squats for 15 seconds, rest 15 seconds, and then do bench presses for another 15 seconds followed by other exercises. Depending on your fitness level, you might do one circuit or several circuits during each workout. Circuit training can be done 2 to 5 days per week depending on how fit you are and how much time you have. Circuits can be made specific to individual sports, such as soccer, baseball, or basketball.
Here are 2 examples of circuit -raining workouts. The first workout can be done at home and the other can be done on equipment at the gym:
