INTERVAL TRAINING
Program Definition
This heart rate feature is designed to gradually elevate your heart rate to the upper end of your selected training range, then gradually decrease your heart rate to the lower end of your selected training range using speed and incline. During the workout, this cycle will repeat sever- al times, creating an interval training effect that is cus- tomized to the user’s desired heart rate training range.
During program setup, there must be at least an 18 BPM difference between the lower heart rate limit and upper heart rate limit to ensure an interval workout.
Benefits of Heart Rate Intervals
To calculate your training zone, use the following formulas: (theoretical max HR = 220 - Age)
Heart Rate Training Range Upper Level
_____________________x 0.75 = ___________________________
Your Theoretical Max Training Range Upper Limit
Heart Rate Training Range Lower Level
_____________________x 0.60 = ___________________________
Your Theoretical Max | Training Range Lower Limit |
By including interval exercise in your regular aerobic program, greater effects are noticed. Your heart and muscles will adapt to the increases in demand by utilizing stored calories for energy more effectively. Dynamic Heart Rate Control may potentially result in more calories expended. It will strengthen the heart, provide stress relief and variety to a workout. This program is more effective in training the body to remove excess lactic acid from the muscles.
How to Use 
Interval Training
NOTE: For best results, use a heart rate strap. If user is wearing a heart rate strap, the machine will automatically use the data from the heart rate strap. Contact heart rate grips may not give an accurate heart rate when exercising over 4 mph.
During program setup, you can use the BACK key to return to a previously accepted parameter.
1.Stand on the running belt; press the 
INTERVAL TRAINING key. The Information Window displays the message “DYNAMIC HR CONTROL”. Press the START or ENTER key to continue.
2.The Information Window displays the message “INTERVAL PROGRAM VARIES SPEED AND INCLINE TO ALTER YOUR HEART RATE BETWEEN LIMITS, SELECT UPPER AND LOWER HEART RATE LIMITS”. Press the START or ENTER key to continue.
3.You are prompted to enter your weight.
■The treadmill will display a default weight of 155 pounds (70 kg). You may enter any weight from 0 to 350 pounds (0 to 135 kg).
■ You can enter your weight using the numeric keypad. Use the 0 
9 keys to enter your correct weight.
