⚖️ Calibration

Introduction to calibration

Two types of calibration help training with Perifit to be tremendously effective:

  • The initial calibration
  • The dynamic calibration

Training with Perifit is tantamount to intermittently stressing your pelvic floor muscles in order to make them stronger (by the physiological principle of  hormesis).

To be effective, the stress stimulus should be applied with an intensity that takes you  beyond your comfort zone. Otherwise, you would only be having fun, but not working out. However, in order to not be detrimental and lead to injuries, bad form, or discouragement, the stress stimulus should not be too high either.

With Perifit, the highest stress stimulus is defined as the intensity of the contraction needed to reach a lotus positioned at the top of the screen.

Both calibrations are tasked with tailoring the optimal intensity to your physical state of the day so that you get the most out of your training time.

Initial calibration

The initial calibration determines the highest intensity to start with. It requests you to relax/squeeze three times to get an accurate measurement of your maximum strength at that given moment.  

For example, if your maximum strength is 200g, Perifit will ensure the highest lotus needs 200g of pressure to be reached. No more, no less.

And if today you can press 800g, the highest lotus will be placed just right for you, too.

Dynamic calibration

But the pelvic floor muscles fatigue quickly, especially when one is new to this type of training. Thus, an intensity that is mildly uncomfortable at the beginning (hence perfect for strengthening) may become entirely out of your comfort zone after a 1-minute play. 

That is where the dynamic calibration comes in. If it detects that muscular fatigue is preventing you from collecting that top lotus, it adapts the intensity of the requested contraction so that the game remains feasible, while still requiring you to strive.

Achieving a perfect calibration


For the initial calibration to be as accurate as possible, you should do it in a body position that you will keep throughout the game. That is, if you calibrated lying with legs bent, keep your legs bent during the game. If you changed position and the bird position seems inaccurate, you should Pause Recalibrate in the new position.

Playing by the rules

Both the initial and dynamic calibrations work by comparing a displayed contraction pattern with an expected one. So, for those to behave adequately, you should play by the rules and follow the calibration and game guidelines.


Troubleshooting calibration

If you can't reach the high lotuses, you could simply squeeze less hard at the initial calibration. Giving 50% of your best instead of 100% will make the highest lotus twice as easy to reach.

You can do this in the middle of a game if needed ( Pause Recalibrate). 

On the contrary, if it is too easy to train, you could try to relax deeper and squeeze harder for all three of the relax/squeeze injunctions in the calibration. Indeed, the higher lotuses are positioned based on the average difference in the applied pressures between the relaxed and squeezed states.
