I want to become a well-rounded martial artist.
I used to train Muay Thai when I was a kid. But 3 years ago I quit and focused on BJJ & grappling. I would really love to combine BJJ with Muay Thai but I fear a negative effect on my grappling skills.
I asked some friends (not really experts) if it's good to add Muay Thai and they replied by saying it'll affect my BJJ in a negative sense. Is this true?
