Should I do Insanity before P90X?

Insanity is a very intense program and is usually taken on by people who have already completed P90X and looking to lose that last bit of fat. Insanity only involves body weight for resistance, and is mostly cardio based. I didn’t start Insanity until after one round of P90X. However, my wife and sister-in-law started off with Insanity and they liked it!
