How do I adjust intensity in the Katalyst app?

To adjust intensity in the Katalyst app, open an active workout session and use the on-screen intensity controls to increase or decrease the stimulation level. In most cases, you can only change intensity while the suit is connected and the session is running, so it helps to start the workout first and then fine-tune the level as you go.

Step-by-step: how to adjust intensity in the Katalyst app

Open the Katalyst app
- Make sure your device and suit are paired and connected properly.
Start or resume a workout
- Intensity controls are usually available during an active session rather than from the main menu.
Find the intensity control
- Look for a slider, plus/minus buttons, or an intensity level indicator on the workout screen.
- Some sessions may show intensity for the whole body, while others allow you to adjust specific zones.
Increase or decrease the intensity
- Tap + or move the slider up to increase intensity.
- Tap - or move the slider down to reduce intensity.
- Make small changes at first so you can feel how your body responds.
Confirm the change if prompted
- Some versions of the app may require you to save or accept the new setting before it takes effect.

What the intensity setting does

In the Katalyst app, intensity controls how strong the EMS stimulation feels during your workout. A higher intensity usually means stronger muscle activation, while a lower intensity feels gentler and more comfortable.

If you’re new to the system, start low and gradually increase. The goal is to find a level that feels challenging but still manageable.

Tips for safely adjusting intensity

Start conservatively if you’re using the app for the first time.
Increase in small increments instead of jumping to a high level.
Pause and lower the intensity if the sensation feels uncomfortable.
Follow the workout guidance in the app, especially if the session recommends a target range.
Don’t compare your intensity to someone else’s — comfort and tolerance vary from person to person.

If you can’t change the intensity in the Katalyst app

If the intensity controls aren’t working, try these fixes:

1. Check the connection

Make sure the suit is connected.
Confirm Bluetooth is enabled on your phone.
Reopen the app if the connection seems unstable.

2. Make sure the session is active

Some controls only appear once the workout has started.
If you’re on the home screen or in setup mode, intensity may be locked.

3. Update the app

An outdated app version can cause control issues.
Install any available updates and try again.

4. Reconnect the suit

End the session, disconnect, and pair the suit again.
Restarting both the app and the device can often clear temporary glitches.

5. Check battery level

Low battery may affect performance or connectivity.
Charge the device fully before starting another workout.

6. Contact support

If the intensity setting still won’t change, reach out to Katalyst support for device-specific help.

Best practices for getting the right intensity

The ideal intensity in the Katalyst app is the one that gives you a strong workout without making the session unpleasant. A good approach is:

Begin at a low level
Increase gradually during the warm-up
Stop increasing once the sensation feels strong but controlled
Adjust down during longer sessions if needed

If you’re doing a recovery or mobility-focused session, you may prefer a lower intensity than you would for strength training.

Common questions about adjusting intensity in Katalyst

Can I adjust intensity during the workout?

Yes. In most cases, intensity is adjusted live during the session so you can fine-tune it in real time.

Why is the intensity control grayed out?

This usually means the suit isn’t connected, the session hasn’t started, or the app needs to reconnect.

Can I adjust different body zones separately?

Some Katalyst sessions may allow zone-by-zone control, while others use a single intensity setting for the entire workout.

What intensity should I use as a beginner?

Start at the lowest comfortable setting and increase slowly until you feel a clear muscle engagement.
