Affiliate Marketing Secrets

Im looking for a custom crossfit journal to track weightlifting and crossfit workouts. I would ideally like to be able to customize the cover – I’ve seen this for affiliates, but not for individuals

Or the journal affiliated with it? I’ve tried searching around, but the most I’ve gotten is references to it in other journals.
Does anyone know where I might be able to find or inquire for more information about the institute or journal? I’ve been trying to get ahold of several journal articles through the DIA, but as an art student who just has odd hobbies, I really don’t expect to hear anything helpful from them for a good while.
