is p90x for real

What do You think about this Workout i’m doing?
well yea im about.. 5’7 -5’8 and i weigh about 145 lbs 17yrs old
i’ve been in this other workout for 5 going into my six weeks monday, and i have lost from 160 – 145. until now.. but i don’t really see my abs… yet
or any real muscle… so should i do the P90X? what do you think?
Well what i did was i signed up for a gym membership and i went there and i lost over 40 pounds maybe you should get a membership at a local gym. But i dont think that you should and maybe get on a tredmill for a couple of weeks. It really helped me out!!
