Does anyone have Nike Training Club for iPhone, iPod, or iPad?

So I have that and I was wondering if I can do the workouts on there. Like the cardio. Because I've been starting up P90X (or I've been meaning to:whoops:) and sometimes I just don't have time to put in a 60 minute workout, so instead can I do the Cardio Burst workout from the Nike attaining Club? Will it be very effective? I'd do workouts from the Get Lean section and Get Focused section. Will I still burn a lot of calories and will it still be just as effective instead of doing the P90X cardio? How many days of cardio does it take for your heart to get very healthy?

Lastly (a bit off topic for this post), how long does it take to see increased flexibility using yoga 2x a week?

I have it enabled, but I never use it. :P
