Brock should follow the JTsunami dieting and exercise principles.
In step one, you cut all proteins and healthy fats. You recieve all of your calories from refried beans, carrot cake and pixxy sticks. In step two, you refrain from all forms of exercise including walking up stairs and to the bathroom. In step three, you begin with a light keyboard work out on getbig. com where you knock athletic and successful people for 8-14 hours daily. Slowly you work your way up to 24 hours a day.
Finally in step 5, you either suffocate yourself with your mouse cord ( great for developing the trapezius) or roll out of bed and break your hip. If you go with option two, you will die on the floor of your bedroom covered in your own waste after starving to death while still logged on to getbig.
Brock has no idea what he's doing.
