It is an important question that comes across the minds of various bodybuilders especially the new ones that how much a muscle should be trained i.e what should be the frequency of training for particular muscle. Now the answer to this questions depends on certain things like what shape or condition the body is. If the body is not in a very good shape, then you cannot definitely go for hard training of muscle. Now what you can do is that you can train muscle more frequently and with the passage of time, as your training gets better, you can increase the intensity of the training as well.
When you train your muscles hard, this means that you put them under lots of wear and tear and lots of repair is needed. So more recovery time is needed because muscles need more rest to repair themselves. Now one thing is clear that proper rest and recovery time is important to allow muscles to grow and get repaired. So for example, if you train your chest muscles on Monday, then you need to give 48-72 hours of rest to these muscles so that they get repaired and growing process is stimulated fast. If you train hard, you need to give more recovery time. So next training for chest muscles should be on Wednesday or Thursday.
If you are training your muscles on daily basis, then perhaps you are wasting your time and this will not bring you any good results because muscles are not getting any time for rest and repair. Particularly, if you are training your muscles hard with high intensity, you must ensure that you do not exercise them daily but after proper time as explained above.
The above mentioned facts about weight training frequency for bodybuilding workouts should be taken care of if you really want your muscles to grow big
