HOW TO PLUG IN THE POWER CORD

USE A SURGE SUPPRESSOR
Your treadmill, like other electronic equipment, can be damaged by sudden voltage changes in your home’s power. Voltage surges, spikes, and noise interference can result from weather conditions or from other appliances being turned on or off.
To decrease the risk of damaging the treadmill, always use a surge suppressor (A) with the treadmill. To purchase a surge suppressor, see precaution 15 on page 3. Use only a surge suppressor (A) that is UL 1449 listed as a transient voltage surge suppressor (TVSS). The surge suppressor must have a UL suppressed voltage rating of 400 volts or less and a minimum surge dissipation of 450 joules.
The surge suppressor must also be electrically rated for 120 volts AC and 15 amps. There must be a monitoring light on the surge suppressor to indicate whether it is functioning properly. Failure to use a properly functioning surge suppressor could result in damage to the control system of the treadmill and serious injury to users.
PLUG IN THE POWER CORD
The treadmill must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.
The treadmill power cord (B) has a plug with a grounding pin (C) (see drawing 1 on this page).
DANGER: Improper connection of the power cord increases the risk of electric shock. Do not modify the plug—if it will not fit an outlet, have a proper outlet installed by a qualified electrician. If you are unsure whether the treadmill is properly grounded, contact a qualified electrician.
Plug the power cord (B) into a surge suppressor
(A), and plug the surge suppressor into an appropriate outlet (D) that is properly installed and grounded in accordance with all local codes and ordinances. The outlet must be on a nominal 120-volt circuit capable of carrying 15 or more amps. To avoid overloading the circuit, do not plug other electrical devices, except for low-power devices such as cell phone chargers, into the surge suppressor or into an outlet on the same circuit.
IMPORTANT: If the treadmill is connected to an AFCI-equipped outlet and your circuit breaker trips repeatedly when the treadmill is used, see the front cover of this manual to purchase an arc filter.

A temporary adapter (E) may be used to connect the surge suppressor (A) to a 2-pole receptacle (F) if a properly grounded outlet is not available.

The lug (G) or wire extending from the adapter must be connected with a metal screw (H) to a permanent ground such as a properly grounded outlet box cover. Some 2-pole receptacle outlet box covers are not grounded. Before using an adapter, contact a qualified electrician to determine whether the outlet box cover is grounded. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician.

EXERCISE GUIDELINES

WARNING: Before beginning this or any exercise program, consult your physician. This is especially important for persons over age 35 or persons with pre-existing health problems.
These guidelines will help you to plan your exercise program. For detailed exercise information, obtain a reputable book or consult your physician. Remember, proper nutrition and adequate rest are essential for successful results.
EXERCISE INTENSITY
Whether your goal is to burn fat or to strengthen your cardiovascular system, exercising at the proper intensity is the key to achieving results. You can use your heart rate as a guide to find the proper intensity level. The chart below shows recommended heart rates for fat burning and aerobic exercise.

NordicTrack NTL14124 1 Commercial 1250 Treadmill - SYMPTOM
1

To find the proper intensity level, find your age at the bottom of the chart (ages are rounded off to the nearest ten years). The three numbers listed above your age define your “training zone.” The lowest number is the heart rate for fat burning, the middle number is the heart rate for maximum fat burning, and the highest number is the heart rate for aerobic exercise. Burning Fat—To burn fat effectively, you must exercise at a low intensity level for a sustained period of time. During the first few minutes of exercise, your body uses carbohydrate calories for energy. Only after the first few minutes of exercise does your body begin to use stored fat calories for energy. If your goal is to burn fat, adjust the intensity of your exercise until your heart rate is near the lowest number in your training zone. For maximum fat burning, exercise with your heart rate near the middle number in your training zone.
Aerobic Exercise—If your goal is to strengthen your cardiovascular system, you must perform aerobic exercise, which is activity that requires large amounts of oxygen for prolonged periods of time. For aerobic exercise, adjust the intensity of your exercise until your heart rate is near the highest number in your training zone.
HOW TO MEASURE YOUR HEART RATE
To measure your heart rate, exercise for at least four minutes. Then, stop exercising and place two fingers on your wrist as shown. Take a six-second heartbeat count, and multiply the result by 10 to find your heart rate. For example, if your six-second heartbeat count is 14, your heart rate is 140 beats per minute.

WORKOUT GUIDELINES
Warming Up— Start with 5 to 10 minutes of stretching and light exercise.
A warm-up increases your body temperature, heart rate, and circulation in preparation for exercise.
Training Zone Exercise— Exercise for 20 to 30 minutes with your heart rate in your training zone. (During the first few weeks of your exercise program, do not keep your heart rate in your training zone for longer than 20 minutes.) Breathe regularly and deeply as you exercise; never hold your breath.
Cooling Down— Finish with 5 to 10 minutes of stretching. Stretching increases the flexibility of your muscles and helps to prevent post-exercise problems.
EXERCISE FREQUENCY
To maintain or improve your condition, complete three workouts each week, with at least one day of rest between workouts. After a few months of regular exercise, you may complete up to five workouts each week, if desired. Remember, the key to success is to make exercise a regular and enjoyable part of your everyday life.
SUGGESTED STRETCHES
The correct form for several basic stretches is shown at the right. Move slowly as you stretch ; never bounce.

  1. Toe Touch Stretch
    Stand with your knees bent slightly and slowly bend forward from your hips. Allow your back and shoulders to relax as you reach down toward your toes as far as possible. Hold for 15 counts, then relax.
    Repeat 3 times. Stretches: Hamstrings, back of knees and back.

  2. Hamstring Stretch
    Sit with one leg extended. Bring the sole of the opposite foot toward you and rest it against the inner thigh of your extended leg. Reach toward your toes as far as possible. Hold for 15 counts, then relax.
    Repeat 3 times for each leg. Stretches: Hamstrings, lower back and groin.

  3. Calf/Achilles Stretch
    With one leg in front of the other, reach forward and place your hands against a wall. Keep your back leg straight and your back foot flat on the floor. Bend your front leg, lean forward and move your hips toward the wall. Hold for 15 counts, then relax. Repeat 3 times for each leg.
    To cause further stretching of the achilles tendons, bend your back leg as well. Stretches: Calves, achilles tendons and ankles.

  4. Quadriceps Stretch
    With one hand against a wall for balance, reach back and grasp one foot with your other hand. Bring your heel as close to your buttocks as possible. Hold for 15 counts, then relax. Repeat 3 times for each leg.
    Stretches: Quadriceps and hip muscles.

  5. Inner Thigh Stretch
    Sit with the soles of your feet together and your knees outward. Pull your feet toward your groin area as far as possible. Hold for 15 counts, then relax. Repeat 3 times. Stretches: Quadriceps and hip muscles.
