- The exerciser's heart rate goes up very high, returns to a lower, but still elevated, state, and then goes up very high again. At no point during circuit training does the heart rate return to its resting rate.
- Circuit training, and interval training overall, increases the amount of oxygen that a person consumes post exercise, and therefore, increases the number of calories that a person burns throughout the day.
- It Challenges your whole body.
- You love cardio but know you should do weights too (or vice versa), and forcing yourself to do an entire workout you don't enjoy can be hard work! Circuit training offers the best of both worlds by allowing you to combine intervals of high-intensity cardio with heavy weight lifting for a comprehensive work out!
- It sends your metabolism soaring! Thanks to High Intensity Interval Training (HIIT) and heavy weight lifting, circuit training kicks your fat-burning furnace into high gear. You'll torch more calories in 20 minutes than you would in an entire hour on the TREADMILL.
- Plus, the after burn effect will have you torching calories for up to 48 hours after your workout ends.
