There are definitely times when more than one day is needed. That is going to depend on how you were training. Another is if you have been over training and then you should definitely take a few days off. Another common reason for taking more than one rest day is following the completion of a competition or middle to long distance race (half marathons and longer). By the way, it took me almost 2 weeks to recover from one half marathon!
It’s always a positive thing when a client wants to know about rest and how much he or she needs. I will tell a client that its ok to take the week off depending on how many weeks we have been going strong. It feels great to let the body heal properly, so we can go for it hard, when we start back up.
Rest/Recovery is why you workout. Longer recovery is absolutely necessary in many situations and if more than normal soreness is the result of a workout. Working out sore muscle groups wastes the previous workout and may result in injury. And for most highly trained exercisers, 5 to 10 days of rest in a row are often very beneficial once or twice a year.
There is much more to recovery than the average fitness instructor understands. I teach a series of CECs on recovery. Many of the students that have taken the class report to me that they experience previously unattained results once they properly apply recovery in their programs.
