Circuit training is a form of exercise that focuses on keeping your heart rate elevated as you perform a sequence of different exercises with minimal to no rest between each repetition and exercise. As mentioned above, this type of training is excellent for improving your cardiovascular health and strengthening various other muscle groups. Circuit training has many similarities to high-intensity interval training (HIIT). HIIT has grown in popularity over the last ten years because of its link to fat burning. Circuit training and HIIT share similar qualities, such as performing exercises at maximum exertion levels in short bursts and targeting various muscle groups during one workout.
A circuit workout typically has a combination of 8-12 different lower body, upper body, core, and cardio exercises, and you perform each exercise for either a set amount of time (30 seconds – 1 minute) or a set number of repetitions (10 – 25 reps) before moving on to the next exercise. The set of exercises are repeated 3-5 times, depending on your fitness ability.
