INTRODUCTION

Congratulations on the purchase of your new APEX Ic8 Computer-Controlled Indoor Cycle from
Diamondback Fitness. You have made a smart choice and are about to enjoy one of the most
effective and technically-advanced methods of cardio-vascular exercise available today.

Founded in 1991 as an off-shoot of the legendary bicycle division, Diamondback Fitness was
in many ways a complimentary addition to the Diamondback brand. One might even say this
extension grew as a natural evolution from classic outdoor bicycle usage toward indoor-based
cycling and cross training. It turns out many fi tness enthusiasts were searching for ways to
maintain conditioning during times of inclement weather or were simply looking for new and
different crosstraining options.

This trend still continues today, twenty years later, as the strong Diamondback brand resonates
with both the boomers who grew up with the bicycles, as well as the younger generations riding
them today.

Diamondback Fitness continues to build upon this legendary brand identity by offering the cardio
enthusiast a full line of upright bikes, recumbents, indoor cycles, and elliptical trainers that offer
great value, high quality and intuitive & visually-pleasing design. Let’s just say, we are already
planning our next twenty years.

WORKOUT GUIDELINES

Good health is an exercise in common sense.

In the study  tled, “The Surgeon General’s Call To AcƟ on To Prevent and Decrease Overweight and Obesity”, the Surgeon
General indicates that 61% of American adults are either overweight or obese. The study indicates that being overweight
increases the risk of health problems, such as heart disease, certain types of cancer, type 2 diabetes among other affl ic ons.

The Surgeon General’s Healthy weight advice for consumers is:

• Aim for a healthy weight: Find your Body Mass Index (BMI) on the chart below.

• Be ac ve: Keep physically ac ve to balance the calories you consume.

• Eat well: Select sensible por on sizes.

Heart rate is an important key to your exercise.

The Surgeon General also released a report on physical ac vity and health. This report dictates that exercise and fi tness are
benefi cial for a person’s health and reiterated the need for exercise as a key component of disease preven on and healthier
living.

If exercise intensity is too low or too high, no gains will be made in fi tness. If the intensity is too low, the stress levels are
ineff ec ve. If the intensity is too high, injury or fa gue may set your exercise program back as you try to recover.

The best way to determine exercise intensity is to accurately count your pulse during exercise. Your heart rate can easily be
determined by coun ng your pulse at the chest, wrist or at the caro d artery on your neck. It is diffi cult to count your own pulse
during exercise, mainly because you cannot count fast enough to record an accurate rate. This Diamondback Fitness 510Ic is
equipped with contact heart rate sensors.

WORKOUT GUIDELINES

APEX Ic8 Owner’s Manual

WORKOUT GUIDELINES

Calculated Maximum Heart Rate & Target Training Zone

Your calculated target heart rate, or the ideal intensity needed to improve cardiovascular fi tness, depends primarily upon your
age rather than your current state of fi tness. If the exercise intensity is too low or too high, only modest gains will be made
in strength and cardio-vascular fi tness. A workout at a very low intensity will not off er maximum benefi ts. Conversely, if the
workout intensity is too high, injury or fa gue may slow the progression of your exercise goals as the body a empts to recover.

Note: It is most eff ec ve to train at a heart rate between 60% and 85% of your maximum heart rate. Maximum heart rate is

calculated as a percentage of your maximum heart rate (es mated as 220 beats-per-minute minus your age).

To calculate your maximum heart rate and fi nd the appropriate target training zone, use the following formulas. For example,
the following es ma on would be relevant for a 35 year-old user:

220 - Age = Maximum Heart Rate (220 - 35 = 185)

60% of Maximum Heart Rate (60% x 185 = 111bpm)

85% of Maximum Heart Rate (85% x 185 = 157bpm)

Based on these calcula ons, the recommended heart rate training zone for this user would be between 111 Bpm – 157 Bpm.

The graph below displays the recommended heart rate training zone for users twenty years of age to seventy-fi ve years of age.

WORKOUT GUIDELINES

WORKOUT QUALITY AND QUANTITY

It is recommended that you accumulate at least 30 minutes of physical ac vity most days of the week. Physical ac vity should be ini ated
slowly and the intensity should be increased gradually. You should select ac vi es that you enjoy and can fi t into your daily life. Having
Diamondback Fitness equipment at home certainly gives you the comfortable and convenient workout you want.

The American College of Sports Medicine makes the following recommenda ons for the quan ty and quality of training for developing and
maintaining cardio respiratory fi tness in healthy adults:

• An ac vity that uses large muscle groups, maintained con nuously, and is rhythmical and aerobic in nature.

• Dura on: 20 to 60 minutes of con nuous aerobic ac vity, including a warm-up and cool-down period, for each exercise session.

• Frequency: 3 to 5  mes per week.

• Intensity: 60% to 85% of maximum heart rate.

In addi on to aerobic exercise, strength training of moderate intensity twice per week is recommended. Women especially may benefi t from
weight-bearing exercises. Select ac vi es you enjoy and can fi t into daily life. Having Diamondback Fitness equipment at home off ers you the
opportunity to work out without going to the gym.

Get a smart start on exercising

Anyone over the age of 35, as well as, younger persons who are overweight, should check with his/her physician before beginning any type of
exercise program. People who have diabetes or high blood pressure, a family history of heart disease, high cholesterol or have led a sedentary
lifestyle should protect themselves with a medical check-up and a stress test, preferably administered during exercise by a health care
professional.

• Always stretch before your workout to loosen muscles, and a erward to cool down.

• The fi rst few minutes of your workout should be devoted to warming up muscles before a vigorous workout, and building your heart rate
slowly.

• A er your aerobic workout of about 24-32 minutes, spend 10 minutes gradually reducing your heart rate with a lower resistance level.

NOTE: Start slow, with intensity low un l you build up endurance and strength. Always consult your physician before beginning any exercise

program.

or decreasing the pedaling resistance to maintain the specifi ed heart rate. This is the defi ni on of
heart rate control. The console will increase the resistance one level every thirty (30) seconds if the user’s heart rate is below the
target. If the user’s heart rate exceeds the target, the console will beep and the resistance will be reduced one level every fi  een
(15) seconds un l the user’s heart rate falls below the target. To protect the user, the console will beep and shut down if the
heart rate does not fall below the target a er thirty (30) seconds have elapsed.

Three (3) of the programs target a percentage of the user’s calculated maximum heart rate (see the sec on  tled Calculated
Maximum Heart Rate & Target Training Zone). The calculated maximum heart rate formula considers age to arrive at an upper
threshold, or maximum. The user will be required to supply their age informa on for these programs to operate correctly. The
computer then determines which heart rate represents 55%, 70% and 90% of the user’s calculated maximum.

28

The T.H.R. (Target Heart Rate) program diff ers from the percentage programs in that the user will set a numeric value for their
targeted heart rate. Resistance will be controlled by the unit to help maintain the user’s target pulse rate.

To select one of the H.R.C. program, highlight the H.R.C. category in the main screen via the UP and DOWN arrow keys. Press
ENTER to accept.

pressed, the console will scroll through the available se ngs; TIME DISTANCE CALORIES PULSE TIME. The user may adjust
any/all of these targets via the UP and DOWN arrow key. To accept the current se ng and move to the next value, press the
ENTER key.

Fitness Test

The 510Ic off ers a pre-programmed test to provide a rela ve measurement of your body’s ability to recover from a
strenuous workout. The program will monitor the amount of  me required for an elevated heart rate to return to
normal. This comparison provides a fast, simple gauge of how fi t you are. If you exercise regularly, you will see your
fi tness ra ng improve.

MAINTENANCE

All Diamondback Fitness products are engineered for years of near-silent opera on. Let noise be your fi rst indica on that a
repair or adjustment is required. Please, discon nue use immediately and contact an Authorized Service Technician or Diamond-
back Fitness Dealer if an unusual noise, scraping, knocking, grinding or vibra on is detected. O en, a minor issue will become a

and chemical-resistant ABS and PVC. The frame is produced of high-tensile steel and protected with an industrial-grade, powder
paint coa ng for the highest level of corrosion resistance. It is important to note however, that perspira on can be extremely
corrosive if allowed to accumulate on the machine. A er training, always wipe down the unit with a mild soap solu on followed
by a thorough drying with a clean towel. Loca ng a small spray bo le and towel near the unit will help ensure that your Dia-
mondback Fitness equipment looks new for many years.
