Hi, Im 21 years old and wanna start some sort of martial arts, starting my research and wondering if u guys can help...

I want something practical, good for self-defense but not some little program, I want something serious that I can grow with and master over the years, that's why I wanna make sure I start one that's right for me.

Also, I live in Toronto, if anyone wants to recommend good places around here that would be really appreciated.

Thanks
