Interval Training: Burn More Calories. Improve Performance. Reduce Exercise Time.

Yes this sounds almost too good to be true.

Interval Training involves alternating between higher and lower intensity in your cardio workout. It could be right for you if you have a good cardio base and want to improve performance or results. If you're just beginning to train, we start by getting your cardio base established first, and prepare your body for the demands of this training. A cardio base is usually established with moderate exercise, 60-70% of your maximum heart rate or a rate of perceived exertion of about 5-6 on a scale of 10*. (A simple estimate of your maximum heart rate is 220-your age, I can give you a better estimate if you give me your age and resting pulse).

Research shows that Interval Training burns more calories than training at a steady rate, partly because it raises your metabolism for 2-3 hours after you stop exercising. The scientific term for this phenomenon is EPOC for Excess Post Exercise Oxygen Consumption. It also seems to cause molecular changes in the muscle that increase fat burning. Interval Training may also improve your performance by increasing your body's ability to remove lactate from the bloodstream, so it can help well-trained people get to the next level. This point is often described as reaching your anaerobic threshold or "going anaerobic". Scientists now believe that "going anaerobic" is a myth, - along with "the myth of the Fat Burning Zone." Remember that you burn more TOTAL calories in the cardio zone than in the fat burning zone, and interval training can help you get there. Numerous studies have shown that for many people, interval training produces better results in less time than steady state aerobic training.

A typical starting interval training program might consist of a warmup followed by 60 seconds of high intensity exercise followed by 90 seconds of recovery at a lower intensity repeated about ten times. As you become more conditioned, decrease the recovery to 60 seconds. In more advanced programs, the high intensity intervals can be 2-3 minutes long, with rest periods equal to or less than the high intensity interval. High intensity exercise generally means that your heart rate is 75-85% of maximum, and the recovery rate is about 60%. To use rate of perceived exertion, you should feel that you're at about 8-9 on a difficulty scale of 1-10 in the high intensity period, and about 5-6 in the lower intensity period.

You can do interval training on any cardio equipment, or with other activities such as running or jumping rope. Beginners may get their heart rate up with walking on a treadmill and varying the incline, while very fit people will need to do something more challenging.

Special Feature: Interview with NYSC Spin Master Rob Merluza

A snowstorm in February provided a long-awaited opportunity for me join one of Rob's spin classes at NYSC Wall Street --- his classes and my evening schedule are usually totally booked. We followed up with an interview:
Q: What's the Goal of Your Class? My classes are tailored to maximize effectiveness in 45 minutes. The focus is high intensity interval training, one of the best ways to maximize results.

Q: What Sets your Classes Apart? The thing I'm known for is that my classes simulate an outdoor ride, simulate real hill climbs. To round out the experience and make it enjoyable, I use tailor each song to the exercise, providing a nice rhythm and beat to accompany the ride.

Q: How do you keep it going? My classes focus on different areas such endurance, strength with increasing resistance, staying in the aerobic zone. I throw in a kicker - sprints - to get the class into a higher zone, increase heart rate and calorie expenditure, really tax the system. Throughout, I'm always cognizant of providing adequate recovery between sprints and intervals.

Q: What else can your students expect to learn? I touch on proper form and technique, improved pedal stroke, body alignment and positioning - so that the body works in synergy with the bike.

Q: Can you tell us some of the benefits of your class? Beginners can expect to burn about 400 calories in a class. They may not do all sprints or have endurance to maintain a high energy level throughout, but will feel a sense of accomplishment, get a good workout, and begin building their aerobic base. Moderate to Advanced students can burn 500-800 calories. I focus on challenging them to increase resistance, go harder on sprints, and maintain a high level of intensity.

Q: What about results? I've had members who've lost 30-100 pounds - including one of your clients who combined my spin classes with your strength training program and had great results. They also gain increased endurance, improved strength and leaner appearance. With advanced riders and triathletes, I focus on creating a "strong engine" for the ride - a combination of form, position, pedal stroke and aerobic base.

Rob's Spin classes are Thursday at 6PM and Friday at 530PM at NYSC Wall Street, advance reservations required call 212.482.4800.
