Workouts are important. As you build muscle you are naturally going to burn more calories. You can’t bulk and gain muscle by eating chips and pizza. You’ve got to eat for your muscles. They need good clean and wholesome food, rich in natural carbohydrates and protein, and yes even a little fat from natural and good sources like almonds and other tree nuts.
You can do all the crunches you want in the gym but if you don’t eat right that six pack is not going to shine through.
Get rid of the white flours, the sugars, the fake cereals, the red meat, the soda, the sweet tea. Replace it with good clean meats, fish, chicken, turkey, brown rice, whole grain oats, whole wheat breads and pastas. Veggies and lots of fruit in whole form. I cannot stress diet enough. This will not only get you fit, but healthy. While we do want to gain lean muscle we also want to build lifelong health so that we are physically fit and healthy.
