You can keep following free booty building programs you find online, however you’ve probably been there and done that. And it hasn’t worked. Guaranteed.
You might get sore and think it’s working but soreness is NOT an indicator that a booty program is working, growth is!
And you won’t see growth with a free program. It will and has already probably failed you.
If you want results, please invest in yourself, your health and your booty!
