Should I stick with it?

I definitely suck at Insanity.. I almost feel like I should go back to 30 DS because I do the complete work out but I feel a hell of a lot more worn out and sweaty from Insanity. Do you think I should stick with the Insanity doing as much as I can or go back to the easier work out where I can do every move, as far as what will help me get into shape better?

Well, if it's easier it's not doing as much, but don't strain yourself, either.

How long have you been doing it? I would give it another week and see how you feel after and try to do it everyday so your body gets more used to it. Or maybe do half a workout then build up to completing one.
