ok what is the best work out including muscle-confusion for a six-pack? (abdomen)?

ok what are the best methods of muscle confusion that can get me a six pack fast, easy, and natural. when i mean fast or easy i can understand it might require a few months but what i mean is the fastest option out of the them all (even if all of them are slow). understand what i mean? so what excersices are best , what time period i should change to the next workout, and if possible, can i gain all this in 3 months? if u need im 12 years old. yea yea im 12 i dont need all this now, but i’ve been hearing that its easier to gain muscle at young age instead of trying to get a six pack at 30 yrs old. also a few of my friends have six packs which amazes me (probably cuz they’re 13 but i dunno) so i just want to try to get a six-pack during the summer for next year. any workouts?
