Fastest Ways To Build Muscle - Rest

This is by far the hardest "way to build muscle fast" for people to understand. It is counterintuitive, but true, that muscle growth begins after you leave the gym.
You can have the best weight training routine and nutrition program in the world, but without allowing sufficient time for your muscles to rest and recover, you will significantly slow your muscle growth.
Even in the business world, not getting enought rest can have a negative effect on profits! For example, if companies required its employees to work 10 hours per day, 7 days per week, 52 weeks per year, the employees would burn out and become less productive. Employees need time off to recuperate. This is why companies allow most of their employees to have weekends off and use vacation time.
In the same manner, allowing your muscles to have sufficient recovery time is one of the fastest ways to build muscle. This allows your body to focus on using the protein from your nutrion plan to repair the muscle damage from your weight lifting program.
While the amount of rest needed to fully recover from an intense workout varies significantly from person to person, a good rule of thumb is to allow 4 to 5 days rest between workouts for each body part.
Not allowing your muscles to recouperate will slow or even reverse the muscle building process. Therefore, getting sufficient rest is also one of the fastest ways to build muscle.
