You don’t put weight into muscle. Weight is weight, and muscle is muscle.

Firstly if you want to bulk and follow a diet for kickboxing, and if your metabolism is high, you’re gonna have to eat more to be able to gain weight

Total calories are significant for building muscle. Of course, that doesn’t mean that you should eat five hamburgers from McDonald’s every day like CT Fletcher did, but try to eat whole and healthy foods.

SECONDLY: After total calories, the second most important factor in gaining bulk is your daily protein intake, which is different for everyone.
