Yeah, but some people, like me, won't push themselves without someone telling them too. I would never do at the gym what I do with Horton or Shaun T telling me to do it. That makes a difference for me.
No equipment, that's the best part. Like I said it's a lot of cardio and a little bit of strength and flexibility. Listen, the ab workout is 16 minnutes and has no crunches or sittups. Most of the stuff isn't hard to do and I'm clumsy. I just really like it.
You sound a little like me to a lesser extent. I'm 6'1 and I stepped on a scale a year ago to see 270. So, I spent some time on the eliptical, ate better, lifted and now I'm down to 220. I started Insanity three weeks ago at probably 225 or so. Like I said, with Insanity, they don't make you feel bad for not killing yourself. They are constantly telling you to take breaks when needed and know your boundries. Are you going to get the max out of it right away? No, but I don't know how else to get there quicker. I did P90X a few years ago and there just wasn't the cardio push.
