The guy's training for MMA, I don't think he's to concerned if there's a little extra pressure on his knees and back. As far as sticking with it, nothing is impossible, and this is certainly not unrealistic. Tons of people stick to p90x, and many others use it as their stepping stone into a bigger world of health and fitness. In this regard I think the benefits far outweigh the stress on the knees and lower back.
