Combining strength and cardiovascular exercise into an interval circuit or HIIT can be more beneficial than cardiovascular or strength training alone because the intensity of the exercises raises the resting metabolism, which can help burn more calories in less time.
Interval circuit training or HIIT prepares the body for “burst” sports, such as golf, that require an intense amount of activity in a short amount of time.
Interval circuit training or HIIT can be less intimidating than a long cardio workout because a person is doing short exercise bursts of 20 to 40 seconds of several different exercises instead of 40 to 60 minutes of only one exercise.
An interval circuit is easy to perform at home, in a hotel room or at a gym. This form of exercise cuts workout time by nearly half.
