its a great starting program as you dont have to create your own routines or cycles, can be done at home, requires no equipment, and is only 25 minutes long, great if you have a busy schedule, its not as hard as Insanity or P-90X, and depending on your body type, you wont have to have a strict diet as you will burn so much calories that a little junk food won't hurt, so you dont have to jump into a huge commited diet with a lesser intense routine, thats not to say you cant eat absolute shit and expect results
