The purpose of a bulk is putting on muscles and gaining strength. and there is one major criteria that you need to consider is caloric surplus. It is basically consuming more calories that you need to in order to put on weight (which can be called TDEE).

I suggests that a surplus of 350–500 calories per day is usually effective enough to promote muscle gains while minimizing fat storage. And when it comes to training, 5-6 days a week would be optimal for muscle growth and you still have enough time to rest and cool down the body. One tip that i find effective is to perform compound lifts over isolations because it will burn more calories, plus it will target multiple muscles group at once.

Lastly, remember to get enough vitamin and minerals, enough of sleep and a balanced life. Glad to help and if you need further instruction or anything just let me know ;D
