Well yoga is amazing as is, and this seems to just take it to the next level with the added cardio benefit.
For someone with serious mobility issues, I can instantly see the benefit. No surprise that someone who actually sticks with the program and follows a strict diet(not really mentioned in the video) will lose that much weight. The amazing part is him being able to walk, and on top of that run again.
So what were Arthur Boorman's problems? Obvious one is scar tissue build up from old injuries that weren't allowed to heal properly. Pretty common problem for military folk. How do you fix it? Break it down and get the blood flowing. Best way to break it down is with compression techniques; best way to get the blood flowing in a way that doesn't hurt(like running would).....would be yoga/stretching. Most of us won't ever sustain bad injuries like that, and our ability to keep moving keeps our blood flowing and the scar tissue from building up if we do have minor issues.
The compression techniques I'm talking about are the foam roller and voodoo bands. Friend of mine had patella femoral pain for over a year. Doctors, therapists, chiropractors, etc, etc couldn't do anything. I think he wore a knee brace for very long time. Had a MRI done, and it showed tendinitis from what they deemed to be overuse. Turns out he had injured the same knee a few years ago on a bad fall. The guy who runs MobilityWOD had posted extensively on ART, or active release therapy, and how voodoo bands could help. I gave my friend a pair, and within 2 weeks of using them he was walking pain free.

My point here is there is no magic involved with this program. Yoga has been around a very long time, and has worked wonders for a lot of people. Professional athletes like Jarome Iginla have talked about using it as part of their workout program with extensive benefits. Tweaking it to add the cardio is nice, especially for those people who can't run/walk/move, so on that part I like it.
If you suffer from chronic knee/back/joint in general pain, I HIGHLY, HIGHLY recommend picking up the book 'How To Be A Supple Leopard' on Amazon. The guy who wrote it developed the idea behind voodoo flossing, and anyone who uses his methods calls them magic.
They aren't magic of course. All he did was go away from the ######ed notion that that solution to overuse/swelling problems is ice and elevation. There is a huge movement in the fitness world right now against icing. No surprising, since it is about the biggest lie out there when it comes to 'fixing' actual problems. It might dull or remove the pain, but it does not FIX anything.
Yoga helps fix problems. The foam roller helps fix things. Voodoo Bands fix things.
I could also use Boorman's struggle with being able to run to go on a rampage against running, and how it is the single worst exercise anyone could do, but I won't.
If you like the program, go for it. There are many others like this out there. Insanity, Rushfit, P90X, etc, etc....and I actually like them despite the lack of attention they give to weight lifting. Insanity is especially amazing, and will kick your ass on most days regardless of what kind of shape you are in.
