Honestly, Tae Kwon Do can be boring until you're a higher grade in it... If I were you I'd wait until about green-belt (This could only 1 year); then start going more frequently.
Otherwise you'll just end up doing a million Sajio-Jirugis
Your first and only priority is to establish if you're at a good place. Taekvando is full of crappy schools and McDojo's.
I'm going to be starting taekwondo and if I really like it I'd like to take it seriously. If I really like it I was thinking of going 5 days a week all under the same club although I think it's different instructors. Is this a good idea? Will it speed up my development and grading? Will it confuse me? Im 16 years old and male if that helps answer. Thanks!
