DH and I had been doing Insanity. We can't keep doing it. :( It is causing a lot of pain in knees, shins and feet. DH also has quite a belly, which makes it hard to do some of the poses for certain exercises.
Don't worry! I'm going to do Turbo Jam and he's going to do P90X. I know that you can modify and do lower impact on Turbo Jam. DH lost a ton of weight before with P90X, so he knows it works. Then, perhaps we'll try again with Insanity, once we are more fit to begin with. :)
