Hi folks, even though a lot of these posts are old, no doubt there will be others newly interested in Mutu system or with diastasis recti...just thought I'd share that I did fork out for the 12 week mutu system. I haven't had the willpower however, to be really rigid and do this every night...I seem to do for a week then give up, not because I don't like it, but because life usually gets in the way! Plus my lack of willpower!!
So, I have about a 3 finger width gap at my bellybutton, but funnily only a 1.5 finger width above and below it...I noticed when doing Jillian Michaels 30 day shred that my lower stmach looked kinda wierd when I was doing crunches etc and not like it should so decided I would stop doing those incase of causing any problems like worsening the Diastasis or giving myself a hernia! I would say that if you chose to ignore your problem, you'll probably be fine and your abs will still strengthen...however if you google abs with Diastasis recti you'll see that a pronounced 6 pack with this problem ain't a good look! So I'd not recommend going ahead until you at least try to address the problem.
So Mutu...as I've not completed it or got past Intensive Level 1 I can't comment for majority of the dvd, but can comment on first level. I do believe that if followed religiously this will address and improve the problem it's meant to tackle as it focuses on pelvic floor and core strengthening plus ensuring you have strong glutes which is important so you don't move about in the wrong way and give yourself backache!
I'd say even just by doing the core exericses and intensive workout maybe 10-15 times over a 4 -6 month period (!) this DVD has definitely made me a lot more aware of things. So in conclusion, I would recommend this DVD! However, I think the pricing is prohibitive and it definitely is overpriced for the evident low budget this was produced with (given simplicity of setup, lack of music variety).
