 I personally do it three times a week minimum. Okay. And I also train people a couple of days a week. And how many of these walking lunges do we have to do three times a week? So as far as how many, I don't really time the count of a rep of a walking lunge. It's usually a distance of a room size, a gym size, a track size. Okay. And you want to do a minimum of two or three sets. Okay. And three times a week. Okay.
