Why are my repetitions not recorded or only recorded incorrectly?

Before you continue reading, please check if your sensor has the latest firmware installed. It is also helpful to use the provided Vmaxpro Barbell Strap to reduce impacts on the sensor with actually every exercise. The measurement technology within an IMU (the technology at work in our sensors), like any other measuring device, only functions reliably within a defined measurement range. Due to environmental influences, impacts or strong vibrations, it can happen that measuring ranges are exceeded within the sensors. These out-of-range conditions cause the measured values to drift and lead to large deviations in the output data or even missed repetitions. In the following, we show most frequent causes and suggested solutions in this context.

The minimum distance defined for the exercise and athlete is set too high. Lower it at least 10 cm (4 inches) below your average distance, which you typically cover in this exercise. This setting is there so that, for example, lifting the barbell out of a rack does not generate a repetition.
If an exercise is not a barbell exercise, the option within the exercise definition should be selected accordingly. Depending on the placement of the sensor, a Trap Bar Deadlift is not necessarily a barbell exercise. Trap Bar Article
Are you connected to a Bluetooth headset or similar during the recording? Some models require so much bandwidth that Vmaxpro can no longer receive enough data to be able to map the repetitions. Try to connect your headphones after connecting the Vmaxpro Sensor within the app.
Only one or a few repetitions of a set are recorded each set. The reason are in 99% of the cases impacts on the barbell or strong vibrations caused by wobbly iron plates. The best example is probably the deadlift. That means, when in doubt, try to let each repetition stand for itself by leaving a pause of up to 2 seconds between repetitions while looking for the whistle icon to appear in the top right corner of the view.
When things feel off, we made good experiences with reconnecting the sensor. Also, you can do what you normally do in the initial calibration without being in the guided calibration. By placing the sensor on each side for 3 seconds at a time, you can override the current calibration. This also can fix certain issues with the sensor.
