Muscles can be exercised every day, but the prerequisite is not to exercise the same part of the muscle every day, for example, the chest muscles can not be exercised every day, but at least 48 hours apart before you can do the exercise. Because most of the muscles need to go through 24 hours to 72 hours to be able to completely ease over, some muscles slightly longer and some slightly shorter. The reason why muscles can be practiced every day, you can divide the muscles into several major parts, such as chest, back, legs, shoulders, practice one part every day, you will not repeat the exercise to the same muscle, and will not affect the muscle growth and muscle quality.
