Kickboxing and BJJ, Kickboxing and Hapkido or Karate?

To be honest these questions have only one answer and its what you are good with. if you love to run and jump you can be good at muay thay as it is an art of speed and accuracy within the punch. if you have good strength dont even bother that can be added onto muay thai. Remember that strength isnt a major factor within martial arts. bjj is also another very very good art which consists of grappling and strains that can break bones and tie people into knots. remember all fights end to the ground so bjj is something you most likely want to go into regardless. as for karate and hapkido i can care less. karate is more based off of kata than anything else and dosent give you the real fight strategy in what would you do in a real life situation. you dont expect to drop kick someone in a real fight because it mostlikely wont happen. with hapkido i am not affiliated. but i do know its more of the movement like water than it matters of fighting. but do not get me wrong both of them are great sports of martial arts. but it wont be something to get into if you want to really fight.
