Insanity- how much can you do?

Georgiawoollin

I bought insanify last Christmas and did it everyday for about 4 months, the results were fantastic, I lost over a stone and gained so much muscle and my fitness levels increased so much. I stopped doing it around exam time and then started going to the gym a few times a week instead. I did it tonight for the first time in about 5 months and died haha, couldn't even get past 30 minutes. Can anyone do the whole thing and keep up with shaun? If you can how the hell do you do it?
