Hi, Marcos,

Thank you for taking the time to share your feedback! We’re really glad to hear that you enjoy the app and the variety in your daily routines.

Regarding the sound in your workouts: to get it back, open the exercise and look in the top-right corner of the screen — you should see a sound icon there. Simply tap on that icon, and the sound will be re-enabled for that routine. This should allow you to hear the audio cues through your headphones, making it easier to follow along and know when to move to the next exercise.

We appreciate your patience and hope this helps you get the full experience of the app again. If you have any further questions or notice any issues, don’t hesitate to reach out to me at adam.support@muscle-booster.io with the subject line "TP review".

Keep enjoying your workouts!

Hi Richard,

Thank you for sharing your thoughtful feedback!

You’ve highlighted an important truth — weight loss and fitness progress are highly individual processes that depend on multiple factors such as genetics, nutrition, and consistency. While workouts play a vital role in improving overall health and metabolism, maintaining balanced nutrition with complex carbs, quality proteins, and healthy fats is key to sustainable results.

We’ve also recently introduced a new “Challenges” tab designed to make your workout experience more personalized and engaging. You can find the Chair Workout Challenge there — it’s a great way to stay consistent and track your progress over time.

For further assistance I will contact you shortly from support@muscle-booster.io.
