Which is better p90x or insanity work out?

Would Insanity work for me?

• Im 17 years old 5'2 Im 120 lbs Im not over weight at all. I know insanity is just cardio which will make you lose weight however Im actually trying to gain weight. I know muscle weighs more than fat, Im trying to gain muscle. My stomach is pretty thin but I want my abs to show clearly. I want my arms to look more toned and my legs. P90X wouldnt really be an option because I dont have acces to the equipment. Would this work for me?

• Answer:

  Hi. Well, i'm almost done with the two months. I started at about 125 pounds and I'm down to 115 now. My core is a lot tighter. My abs aren't defined yet but they are definitely way tighter and i'm happy with the results. I notice a huge difference in my shoulders and arms. They are toned. Almost too toned. I haven't noticed a huge difference in my legs though. Its a great workout. I would definitely recommend you give it a try. Overall my body is much tighter and i'm glad I did it. Btw I'm 5'4.
