For a solid 3 months, i went to the gym about 5-6 times a week and just did heavy lifting. I ate nothing but carbohydrates and protein. Lots of pasta and meat. Especially Whey protein. After the three months, I got sick for about a week and didn't lift. after that, i felt it was time to start leaning down. Now is my leaning down period, it consists of mainy doing crunches, pushups, and running. I eat a lot less protein becuase I don't want to gain the weight and I watch the carbs. A lot of salads now too, including sushi as a treat cuz rice is full of carbs. Anyways, my plan was to bulk up in winter, then lean down in the summer. I was really big in teh winter (muscle wise) so that when i lean down and naturally lose muscle, I'll still be somewhat big and not be thin without any muscle mass.
