The simple truth about building muscle is that it cannot be done without sacrifice. The sacrifice comes in the form of blood, sweat and tears needed at the gym or at your home gym. But that hard training is completely useless if you are not going to be eating correctly.
The only way that you are going to get the benefit from your hard training is by eating a well-balanced meat at least 5 times a day. If you have been training for more than a year it is going to take 5 days of hard training for at least an hour at a time. The routine needs to be correctly split so that you are not working the same muscle more than twice a week.
If your objective is to only build muscle then you can do away with any cardio that you might be doing as it is not required. If you are training with weights correctly then you can increase your cardio output by simply reducing the rest period between sets.
Probably the most important aspect of gaining muscle is the form that you use. Training with the correct form is vitally important if you want to avoid injury and continue to add muscle on a continuous basis. If you have been training for more than a year and you are still not 100% sure of what correct form is then you should ask someone at your gym who looks like they know what they are doing.
It is vitally important that you always concentrate on what you are doing and that you squeeze the muscle you are isolating, no matter what body-part you might be training. If you are isolating your biceps when doing a dumbbell curls you need to always make sure that you manage to make that extra squeeze of the biceps at the end of each repetition.
Top professional bodybuilders will tell you that muscles are built in the kitchen and not the gym where they just get broken down. Building muscle means knowing how to prepare the required complex carbs, protein and the essential fats that you need. The planning as well as the preparation of your meals before you leave home is the key to gaining muscle permanently.
The truth is that gaining muscle on a permanent bass is not easy but it takes planning and following a system that is constantly been tweaked for an improvement. It is not for the feint-hearted and needs a dedication that only comes with a sincere focus to improve your body by building muscle.
