If you’re fat eat in a 500 calorie deficit, if skinny a 300-500 calorie surplus if skinnyfat or average either do body recomposition (go to the gym whilst eating at maintenance-to turn fat into muscle) or pick one kf the other options depending on whether you want to prioritise being strong/big or lean.
Pick a good workout split (U/L, PPL and FBEOD are good ones) and go by an established program. Do cardio sometimes and don’t skip legs. Be consistent and results will come.
Eat 1g of protein per lb of body weight and make sure you get enough of the rest of your macro and micronutrients. If you’re skinny and trying to bulk and find it difficult incorporate mass gainer shakes.
