- Manual
- Custom
- Hill
- Fat Burn
- Cardio
- Interval
- Heart Rate Program 1 and 2

IMPORTANT: Always consult your physician before participating in any exercise program or regimen.
Available Programs
Manual Program
A manual program requires a time frame set before starting. You may also choose to enter your age and weight. Speed and incline are adjusted manually while running. Press START to begin workout.
Preset (Built-in) Programs
Preset programs have speed and incline changing profiles, which you can find on the program preview.
To get more info on each program, tap on the program name. Once selected, tap PROFILE to preview the program speed and incline settings. Press ENTER to select a program, or tap the < / > arrows to scroll through the other available programs.
Custom Program
A custom program allows users to create customized speed and incline changing profiles. Once the profile is defined, choose target time and maximum speed, so the intensity adapts accordingly. Levels may be changed manually at any time during the workout.
- From the Exercise Programs list, select Custom program. Press ENTER to begin customizing the program with your personal data, or press the START button to begin the program with the default settings.
- To adjust speed and incline profiles, use the on-screen interface to achieve desired workout profiles. Once complete, press NEXT to save and continue.
- The following screens will ask you to enter the desired time, the user age, and weight. You may use the default values, or adjust as needed. Press START once complete to begin your new custom workout program!
Hill Program
This program follows a triangle or pyramid type of gradual progression from approximately 10% of maximum effort (the level that you choose before starting this program) up to a maximum effort which lasts for 10% of the total workout time, then a gradual regression of Speed back to approximately 10% of maximum effort. Incline levels are gradual and sustain progression. Maximum incline occurs in the middle of the workout and lasts for 10% of the duration.
Fat Burn Program
This program follows a quick progression up to the maximum speed level (default or user input level) that is sustained for 2/3 of the workout. This program will challenge your ability to sustain your energy output for an extended period of time. Incline levels are quick and sustain progression up to the maximum value (default or user input) for 90% of the workout duration.
Cardio Program
This program presents a quick progression up to near maximum speed level (default or user input level). It has slight fluctuations up and down to allow heart rate to elevate, and then recover repeatedly, before beginning a quick cool down. This will build up your heart muscle and increase blood flow and lung capacity. Inline levels in this program are moderate. There are several elevation spikes at different points of the workout (segments 4, 9, and 14 are maximum elevation for this program).
Interval Program
This program takes you through high levels of intensity followed by recovery periods of low intensity. This program utilizes and develops your “fast twitch” muscle fibers which are used when performing tasks that are intense and short in duration. These deplete your oxygen level and spike your heart rate, followed by periods of recovery and heart rate drop to replenish oxygen. All of your lower extremity muscles will be equally challenged throughout this program. The incline alternates between 25% and 65% of maximum elevation.
Heart Rate Programs
See our article: "Utilizing CT850ENT Heart Rate Features."
5K Run and 10K Run Programs
Both speed and incline are controlled by the user. Increase or decrease levels at any time during your workout. When the program begins, the distance will begin to count down; once it reaches zero the program ends. Note: The speed readout is in MPH unless the console is set to display metric measurements.
HIIT Program
The High Intensity Interval Training ("HIIT") program takes advantage of the latest trend in fitness. During this program, you will perform short bursts of high intensity sprinting followed by short rest periods. HIIT is a fully customizable interval training program. Users can enter the number of intervals, time of each interval sprint and rest periods and the work intensity of the levels. To set the program:
- Select the HIIT program, then press ENTER to begin customizing the program with your personal data. Set the number of intervals you want to do (default amount of intervals is 8). One interval equals 1 sprint and 1 rest segment.
- Next, set the interval time (sprint time and rest time). You may to select the sprint time or rest time from 20 to 90 seconds. After the interval time is set, set the intensity training to sprint speed and rest Speed. This is the resistance level you will experience during the program.
- You may now press START to begin the HIIT program. The program starts with a 3-minute warm-up period with the speed set to 50% of the sprint speed selected previously. You can manually adjust the speed during warm-up if you wish.
Fitness Test Programs
When the Fitness Test button is selected from the Exercise Programs Menu screen, the screen displays the different preset tests available: Coast Guard, Navy, Air Force, Army, Gerkin, Marine Corps, and Physical Efficiency Battery (PEB). Tap the test you would like to begin.
Air Force
A timed 1.5 mile run. You control the speed manually. Maximum time allowed to pass the test is shown on the table:
Army
A timed 2 mile run. You control the speed manually. Maximum time allowed to pass the test is shown on the table:
Navy
A timed 1.5 mile run. You control the speed manually. Maximum time allowed to pass the test is shown on the table:
Marines
A timed 3 mile run. You control the speed manually. Maximum time allowed to pass the test is shown on the table:
Gerkin
The Gerkin protocol, also known as the "Fireman’s Protocol," is a sub-max VO2 (volume of oxygen) test. The test will increase speed and elevation alternately until you reach 85% of your Max heart rate. The time it takes for you to reach 85% determines the test score (VO2max) as shown in the chart below. Note: Use a heart rate strap for best results.
Physical Efficiency Battery (PEB)
A timed 1.5 mile run. You control the speed manually. Maximum time allowed to pass the test is shown on the table:
Coast Guard
A timed 1.5 mile run. You control the speed manually. Maximum time allowed to pass the test is shown on the table:
