I just started Insanity with DH. Not the same but I can still join in for support.
DH needs to lose quite a bit of weight and although I am not overweight at all (5' 4" and 110 lbs) I am NOT in great shape. We are also working to clean up our diet and as soon as I can afford a juicer I am starting doing the mean green juice for breakfast since my veggie intake could use a boost.
The only time you should look in your neighbor's bowl is to make sure that they have enough. You don't look in your neighbor's bowl to see if you have as much as them.
