Op here. I don't think there's a file in existence that really does what I want with this. Closest I have found is the one I mentioned originally, curse feminizing run, but I hate running, and it's not a real hypnosis that puts you under first.
I've thought about maybe picking a hypnotist to make a custom file, but don't know who I'd use. Wish N1kk1 F4t4|3 was still in business. Any suggestions? Maybe a female hypnotist who is really into fitness in her personal life? Maybe a TTS type file?
I'd want one that has you watch fit women around you for inspiration, types of food and portion sizes they eat, the fitness apparel they wear. Follow Tumblr pages for female fitness for inspiration. A file that encourages you to learn to love the tight hugged feeling you get from sports bras, yoga pants, panties, etc. How much better women's fitness apparel is to workout in than guys basketball shorts and t-shirts etc. How panties hold your junk in place and that's better for working out.
Then also encourages you to follow a workout routine that is more likely to give you a more feminine physique (toned, small waist, big butt, not bulky, etc). Maybe has you pick a female fitness model as your ultimate inspiration or something. I'm thinking bodyweight/hiit/interval type workouts, mixed with some yoga for flexibility.
Then finally does something to keep you at it. The don't quit, get addicted to this fitness plan type of thing. Maybe feminization leads to working out which leads to feminization so that it's a circle you're happily trapped in.
