Heyy looking to gain weight

To gain weight you need to eat a surplus. Think about your calories, make sure you meet your macros. 40/40/20 is a good split for most but I eat more protein than that- just find your own needs. The surplus calories will go to muscle repair. You grow muscle when resting, not when at the gym.

Lift heavy, lift religiously, and get plenty of protein.

StrongLifts is an excellent beginner program to pack on strength and size.

What is your diet like at the moment? will give us a better idea on how many calories your intaking

When I was on 2000 a day my weight was only maintained but when I go over that I start to gain a little.

I know men tend to need more calories so 3000 is probably a good start (if your not exercising much, if you do any activity you need to add calories to cover it)

eat under 1200 calories to cause starvation mode and weight gain
