How to do bodybuilding for effective muscle gain?

Single muscle workout per day with a gap of one day after each workout - really worked for me, but then it's not a good idea if you are trying to shed some fat. It's only great if gaining muscle is all you have on mind.

There is nothing right or wrong with regards to weight lifting. All methods have proved to work and give astounding results. Whether a full body workout or a split in upper body one day and lower body the other day or like two body parts a day. Single muscle groups with one-day gap before another muscle group if lifted heavy. The stronger you will lift, the more recovery period/gap the muscle will need, so if chest is done heavy today, 5 muscles groups later, it will be chest again after 12-14 days. This one works, miraculously and will certainly show results or if you want to do each muscle group, once or twice a week, then you have to follow any periodization program. Always remember, we do not grow in the gym, we stimulate our muscle there. We only grow in the BED (while resting/sleeping). In the gym, we get weaker as our muscles are exhausted and cells broken. We leave the gym, TIRED.

What is the term "FUELING" in bodybuilding? What does pre workout and post-workout fueling means?

Fueling is just taking in nutrition that supports muscle building. Keeping fueling in mind, you eat particularly that stuff which is required for your muscles to grow. Now taking in nutrition before weight training is called pre-workout fueling and after it is called post﷓workout fueling. There are whole a lot of types of fueling and it generally depends on what program you are following and how you want your body to be. Bodybuilding involves future planning, as you work out today to see your results tomorrow.

Why fueling is important in bodybuilding?

Fueling is important whether it is done before or after a workout but when you are focusing on gaining muscles, fueling becomes much more important after a workout. The thing is when you are in the gym you work your muscles and then your muscle tissues get ruptured. Now in the post work out period, they tend to grow by repairing back those ruptured tissues so at the recovery time, you need to have the nutrients to fuel up the recovery process, so fuel up your body with proteins, vitamins, minerals and adequate amount of water to get the most of the muscle growing process.

Fueling is very essential pre and post workout, especially if you focus on gaining muscles and you got to have some basic nutrients inside you, about 30 minutes max before a good muscle blasting workout, but definitely, a post workout meal/shake is so very important. I do not take whey protein; though it is 100% safe and effective. I rather being a foodie take my proteins from natural food and it has worked for me all these years. You may take if you think you will mange this way. What I use to fuel my body before a weightlifting session is I prepare an energy drink, made of 2 tablespoons of Protinex, milk, coffee, cocoa powder, sugar free/aspartame, Bournvita, boost of each of them and then pour some boiling water on it. I then have a handful of peanuts and a banana. This can work for anyone and it is my drink. You can also look for any other alternate one, but always remember that a drink should be easy to digest and would not jump while you are pumping iron.
