you should always train with martial instructor because any martial art is learned practically not from books and online videos etc
if it is female instructor yes
if it is male instructor better to just stay home
and train from youtube
If supplements matter this much to you clearly you needed intervention.
Why should you train?
Why should you train with a martial instructor.
1. He allows the whole clase 10 students to take what ever protein or creatine supplements they want.
2. He the martial instructor doesn't want you to take any supplements.
Why should you train with a martial instructor who lets the others in class take supplements except you.?
