Curling.. I've done it before.
IT is not easy...it takes EXTREME planning and Dedication. You seriously need to eat like a machine, have plan OUT EVERY LITTLE FUCKING THING.
eating 420grams of protein daily, ,being full ALL tha time, you get to start HATING food, you feel bloated constantly. It sucks... but it was all worth it. If i do it again i might throw in just a little extra light cardio in the morning and take ginger root for protein digestion.
