Keep in mind, I'm not looking to compete. Just trying to become really skilled at those disciplines while getting myself into really good shape.
What do you mean by KB? Kickboxing? I was planning on supplementing my Muay Thai with boxing, I'm just afraid that my Striking won't be as good as it could be because I'll be rolling 4x a week? Any thoughts?
Definitely keep it in mind though, when I started out I thought the same, just be the best physically as I can while training hard.
As soon as I started competing, the camps really upped my skill to the next level, looking back, had I not done that, my skillset and conditioning would never even reach the point it is today.
KB is kickboxing.
Well there's only so much hours in a week you can do. I advise focusing on one primary, and having a bit of the other, its up to you. When you're more experienced, you can get away with more since you're more conditioned. For physical conditioning, focus on both low and high intensity work, both are needed as we use both energy systems. There's no one or the other.
But overall you'll find what your "style" is with time; My case, on paper I seemed like a good candidate as a BJJ'er (very flexible, strong hips and glutes) but actually its something completely intuitive for me. Same with kicking. For me wrestling, boxing, and clinch fighting comes much much more natural than kicking, and BJJ.
So only time will tell what you really are, maybe you're interested in striking, but could be a very natural wrestler-boxer
