Not all of our workouts have sounds integrated - only Tabata and Paleo Run.
If you have an iOS device and are not hearing any sounds during these workouts please can you do the following:
1. Check that the physical mute switch is disabled on the side of your phone (you should not see the red stripe)
2. Once the mute switch is disabled, push the volume all the way up
3. Check that there are no speakers connected via Bluetooth
4. Ensure that music/sounds are activated before starting the workout
This is most common cause of the loss of sound on iOS devices, however, if you still can’t hear anything when you start the workouts, please try flipping the mute switch and raising the volume again.
