the big thing is to STRETCH that muscle before and after you work it..... so now, you stretch a 4 inch muscle out to 4.5 inches....and increase it fro 2 to 2.5 in diam..... and then you stretch it to 4.75, and then 5 inches long....but still increase it's girth and you exercise..... and you get that much stronger.
I've gone from using 70 lbs on my leg curls to 90 lbs in just 2 weeks.....by doing specific hamstring stretches before I do strength stuff.
pretty cool.

I've been doing that P90X workout routine and stretching is very large portion of the workouts. That probably explains why it puts so much emphasis on stretching.
