Why is Boost providing biofeedback even when I am not activating my Kegels muscles?

It’s probably not calibrated to your current body position; you can manually recalibrate at any time by briefly pressing the Power button on Boost, or while you’re in a workout by pressing the Calibrate button in the app. Always make sure that your pelvic floor muscles are fully relaxed (and try to have good posture) when you calibrate.

The other possible explanation is that you may be shifting your weight by leaning around slightly -- this will change your weight distribution on Boost and thus change the reading, so it’s important to have good posture and a quiet / still body position when you’re doing workouts. If you do shift your weight or adjust your body position during a workout, just tap the Calibrate button.
