How long you should let your muscle heal before lifting weights again?

If you're really hitting your muscle hard with heavy weight and going to failure and using advanced techniques such as drop sets and forced reps and staying in the 6-10 rep range, 0nce every 5-7 days is pretty much the accepted norm...however there are exceptions based on training intensity, volume, and genetics...If your really hitting it hard you don't need to be doing more than once every 5-7 days because your body won't recover and then you won't make any prominent strength or size gains, if you're not training really intense but you're using alot of volume 20 sets or more per workout then you don't need to do much more than once every 5-7 days, but some people have great genetics and there body allows them do train twice every 5-7 days, I wouldn't reccomend it for most, but for some it can be effective. If you're not training intense or with alot of volume and you're not really that sore the next day, then you could probably afford to hit those particular muscle as many as three times a week. Like monday, wednesday, Friday.....you would never wanna train the same muscle two days in a row, with the exception of LIGHT ab training.
