Yes, Sara, you're right. Anything from 1 to 2 times a week is good for muscle building. 3 times a week is too much, because it will not be allowing enough time between workouts to grow. Muscles that undergo weight training with heavy weights (for the purpose of building) need 72 hours of rest (which is 3 days). For optimum growing INSTEAD of strengthening, I would recommend this routine be done twice a week, and if not twice, do it only once a week. It's better to have more days of rest than needed than it is to interrupt your muscles' growing period.

This routine should be done more than twice a week if a person wants more to be toning these muscles, as opposed to building them. But, it is important to remember that building muscles only applies to the case in which you use heavy weights (you will know the weight is heavy enough if you cannot finish more than 8-10 reps per set with the weight of that certain exercise. If you cannot do more than 10 reps with that weight, it is a good weight for you!!). If a person is using light weights, they will not be needing the resting time because they will not be needing it to grow as weight trainers do. And so, if a person wants to do this routine with light weights, they might as well do it three times a week... but they will not be getting a great build mass from it. They will just be toning.
