What sports club should I join?

Sounds like you hit a wall in your training! Almost everyone goes through it during their training. When I first started my training I enjoyed the forms/patterns. I then concentrated mainly on sparring and then the injury's occurred. I again started to learn forms and advanced in rank. There is more to martial arts than just fighting. If you start boxing,you would be in for more violence and pain besides,you would risk your looks as well because boxing is a art that trains to punch to the face over and over again. I would recommend that you continue training in the art that you.ve been training in. SuaKaow
