I really, really hate it when an app uses push notifications as a marketing channel
I understand you have a web shop where I can buy gear I need for some of the exercises, but pushing web shop notifications is just plain annoying!
The best time for suggesting web shop is when I genuinely need the stuff you are selling in your web shop. When I decide to swap an exercise because I don’t have the gear necessary for the exercise or when I am opening an app between sessions.
Even then, the placement of product ads is a subtle art and it is too easy to go overboard and make me stop feeling like I’m using a fitness app.
