Could you do this with regular Patreon? I am not familiar with details how exactly it works, I guess you are supposed to provide some media to your subscribers, but I guess you could simply publish videos from your training, or make a vlog before/after a competition. The idea is that people would not pay you because the videos are super awesome, but simply because they are your fans. The subscriber tiers could be like "sponsor", "sponsor who gets autograms", and maybe something special for those who pay really lot.
