Flat to fab: has anyone actually transformed their to be bigger and rounder etc?

well you can always read stuff online on how to make your bigger rounder perkier and ier (getting a like jlo, kim k, jessica biel) but has anyone actually tried doing lunges squats sprints and stair climbers etc all that stuff you can find online that has actually changed the way your looked? im not talking too muscular. but actually big and round and plump looking. i also read rubbinh fish oil and vitamin e helps your get bigger. has anyone actually made a change and can share how they did it? thanks
