is it possible to make a Graduated subscription ?

Hello,

I am creating a fitness application and i would like to charge subscribers depending on how often they complete their workout.

Rn my initial guess i tro create many products like this:

.. and everymonth to show them their next product based on how often they complete their workout the last month.

But it's not ideal for the conversion rate and i would like to know if it's possible to :

Use subscriptions and auto apply a coupon reduction on their subscription ( % based on their use ).

Any ideas ?
