Can I sort My Workouts?

If you are using the iPhone app, you can sort workouts so that your favorites appear at the top of the list. Find and tap the star icon on a workout in the My Workouts screen. The star icon will now appear white. All “starred” workouts will appear at the top of the list.


What does my workout score mean?

The workout score measures your compliance with staying within the coach's target zones during the workout. For example, a score of 50% indicates that you were in the target zone half of the time. A score of N/A indicates that the workout is not measuring your score.


How does the screen lock work?

You can lock the screen when running a workout by selecting the lock icon located at the bottom center of the Workout screen. This allows you to hear audio stats/prompts by tapping anywhere on the locked screen. It also keeps the screen active during the workout. Simply swipe to unlock the screen.


Why doesn’t my Apple Watch show my correct heart rate?

The Apple Watch differs from most heart rate monitors as it only measures heart rate every few seconds, rather than continuously. Due to the technology of the device, there may be a slight delay in the heart rate display in the TRX APP. Usually, your heart rate graph will populate with correct information at the conclusion of the workout.


How do I know if my phone is compatible with the TRX APP?

The TRX APP is compatible with iPhones and Android phones that support Bluetooth 4.0. However, with so many manufacturers and models of Android phones, occasionally there are models that are not supported due to resolution or other factors. If a new user cannot find the app in the store, their phone may not be supported. In this case, contact our team so we can confirm.


Which heart rate monitors are compatible with the TRX APP? 

The TRX APP will connect to third-party heart rate monitors that use a Bluetooth 4.0 signal and that are non-proprietary.

Please note that proprietary heart monitors, including Fitbit and Garmin devices, will not connect to the TRX APP. 


Subscription Information

You can choose to sign up at a price of $4.99 per month or $39.99 per year.


What do I get with my subscription?

Every TRX APP subscription includes full access to our entire library of workouts and training packs, as well as all special features including TRX MAPS and the VO2 Max calculator.


What if I don’t have a subscription?

Without a subscription, you will have access to six pre-selected workouts as well as Tracking Only workout option. You can still access some MAPS features, including scores. Users without a subscription do not have access to the VO2 Max feature.


How do I sign up?

Follow these steps to sign up for a TRX APP subscription:

1. Open the menu ☰ and tap the Membership option. A pop up window will appear with pay options.

2. Select the "$4.99 monthly" or "$39.99 yearly" option.



Connecting to a Heart Rate Monitor

Follow the steps below to sync your heart rate monitor with the TRX APP: 

1. Turn on the Bluetooth option in your phone's settings.

2. Wear your heart monitor per manufacturer requirements.

3. Tap the menu icon ☰, then tap Connect Sensors.

4. Your heart monitor should appear in the list of devices. Tap it so it shows as "Connected."


Don’t See Your Heart Rate Monitor?

If you do not see your heart rate monitor in the Sensors screen, make sure it is turned on (if required), being worn properly, and has battery power. Turning your Bluetooth setting off and on or rebooting your phone/heart monitor may help. If you’re still having trouble, we recommend testing a connection to another compatible fitness app to confirm if it is a hardware issue, in which case you should contact the hardware manufacturer for support.


Setting Your Heart Rate Zones 

Some workouts in the TRX workout library offer responsive heart rate training with prescribed heart rate zones. If you have a Bluetooth heart rate monitor, you can get the most out of these workouts by completing the Calibration Workout, which will set custom zones based on your personal fitness level. Before you begin, prepare for 20 minutes of uninterrupted running/walking.
Complete these steps to calibrate your heart rate zones:

  1. Select the main menu icon ☰, then select Connect Sensors.

  2. Wear your heart rate monitor according to manufacturer instructions. Wait for the device to appear, then tap it to connect. Tap Close to return to the home screen.

  3. Select the My Workouts button, then select Calibration Workout (or Set Heart Rate Zones’).

  4. Select Start and follow the prompts for the duration of the workout.

  5. Once you’ve completed the workout, you can view your calculated zones by navigating to the main menu ☰ > Settings > Heart Rate Zones.

  6. Select Latest Calibration to view your calculated zones.

Note: Instead of setting your zones through the calibration workout, you can choose Calculated Default (estimated from your biometric data) or enter a Custom Value if you already know your Lactate Threshold.


VO2 Max: Your “Fitness Number”

TRX can provide an accurate estimate of your personal VO2 Max number whenever you complete outdoor running/walking workouts with a heart monitor. VO2 Max is a measure of aerobic capacity, or the maximum rate at which the body is able to consume oxygen during exercise. It is a reliable indicator of cardiovascular fitness. The upper limit of your VO2 Max depends partly on your age and gender.
TRX can determine your VO2 Max (i.e. fitness level) to within 96% accuracy of a laboratory test. 
Your VO2 Max will be calculated each time you complete an outdoor running workout with GPS running and while wearing a heart rate monitor. But we've also designed a workout specifically for calculating your VO2, as described below.

VO2 Max “Fitness Number” Workout
In your My Workouts screen, find Your Fitness Number. Complete this workout with a heart monitor to receive a VO2 Max result. Your workout results screen will show your fitness number at the completion of this workout, and you can view your average score from your profile.

For a shorter, walking version of this workout, search for the Fitness Number Walk workout using the search tool. 

Reviewing Your VO2 Max Results
To find your VO2 Max result, navigate to the main menu ☰ , and tap your profile picture. Your most recent VO2 Max will be listed as "My Fitness Level."

Note: Your VO2 max will not be calculated with an indoor treadmill workout. Distance tracking via GPS is necessary to obtain a result. 


Managing Your User Profile

Update your profile at any time to update your list of workout recommendations. Follow the steps below:

  1. From the app home screen, tap the main menu ☰, then tap your profile picture.

  2. Your Profile screen is where you can fill out data about your workout preferences. You can select your preferred activities, workout duration, and fitness level.

  3. Tap the x icon, then tap the right side of the screen to return to the home screen. 

  4. See Recommended Workouts.


My Workouts Screen

My Workouts houses all of your downloaded workouts, and can be accessed from a link on the home screen. Once you download a workout to your My Workouts library, you can access it any time without a network connection.

My Workouts includes links to the following:

  • Tracking Only workout

  • Calibration Workout

  • Your Fitness Number workout

  • 6 free pre-selected workouts


Tracking Your Own Workouts

Using the Tracking Only option, you can track your time, distance, speed, heart rate, and calories burned, without doing a coached workout. Find this option on the My Workouts screen. Keep in mind that you must have Location Services turned on to track distance and speed and you must have a heart monitor connected for a calorie estimate. 


Apple Watch

The TRX APP for Apple Watch can be used in two ways: as a heart rate monitor in tandem with the phone app, or on a stand-alone basis without the phone present. You must have the TRX APP installed on the Apple watch in order to use it as a heart rate monitor. If you prefer to do workouts without your phone, you can sync up to three workouts at a time to the Apple watch and complete them, using a Bluetooth headset to hear audio coaching.

To send a workout to your Apple Watch, tap the ADD watch icon next to the workout in your My Workouts list, or on the workout information screen.

To ensure the app works properly, connect TRX with Apple Health and enable heart rate, distance, and workouts in the Sources section of Apple Health. Make sure to turn on both READ and WRITE categories.

Playing Music

You can use a third party music player to listen to music during your music. It’s best to start the music player prior to starting a workout in the app.

Additionally, for iPhone users, the TRX app will work seamlessly with the music currently stored in an iTunes account. Here’s how:
1. Tap Start + Music when beginning the workout, or if you've already started the workout, select the music note in the lower right corner. This will open your music player, which allows you to adjust volume, play, pause, and cycle through your music selections.

2. To set or change your music selections, select Change Music. From here, you can select and filter the music that streams to your TRX app by choosing an iTunes playlist or artist.


Adjusting Coaching/Music Volume

If you are finding that the music or coaching volume needs adjusting, take the following steps to adjust the audio balance:

Tap the main menu ☰, then select Settings > Workout Audio. Here you can set the volume balance between Music and Coaching. You can also set the information that is provided for on-demand, periodic and event stats.

While a workout is in progress, you can adjust the audio balance by selecting the gear icon to the left of the workout control buttons, and change the balance by sliding the dot toward "coach" or "music."


Partner Apps

TRX will send workout data to certain workout apps if they are connected through the Partners section of the main menu. TRX will also capture steps data from certain fitness accounts.
