I'm doing the knee ability zero program. Currently I spend about 40-45 mins 3 times a week doing the program. It's 15 mins warm-up with backwards walking and then about 25-30 mins of exercises. I'm sure if I was more efficient and didn't take as long of rests between things I could shave significant time off of that. Depending on where you are at in the progression it's shorter or longer. I'm not yet at the stage where I can do the patrick step-up to full ankle bend so I'm not yet doing the ATG split squat. So as you progress the time commitment gets a little longer as you meet the requirements to begin certain exercises. This time is including various stretches that are included as part of the workout and which I view as a key element of the program. There are also additional upper-body and off-day stretching routines that you can do on off-days, but I am personally just doing yoga on off-days so I can't give you a review of those aspects of the program.
