How Much Does Nutrition Affect Fitness Levels?
What I mean by this is if a person is an athlete, how much does good nutrition help performance and development?
What is the best kind of workout routine?
How often should one run to optimize endurance? (Is everyday the best?)
How often should one lift weights? Every other day for upper body and every other day for legs?
How often should one do ab work? Everyday or every other day?
What are the best types of foods to eat for becoming a better athlete?
Take into account that I am a female who is already very active and has good fitness, but is looking to develop more for college soccer.
