In one sentence, describe what the following article is about:

You'll never beat a five minute mile without a plan and proper schedule. For the best results, you should be training almost every day, incorporating different exercises.  Start your week with a distance run, running for at least 40 minutes or about 3 miles, and gradually increasing that as you train. Take the next day to rest or do some other training like yoga or weight lifting. Pick a few days a week to do interval or hill training, followed by another day of rest or cross training. In order to get your body into the right shape for a 5 minute mile, eating the right diet that will give your body energy is important, and it will help it to recover after training.  Get the right proteins through eggs, sweet potatoes, salmon, and chicken. Proteins like salmon contain ingredients like omega-3 essential fatty acids which increase heart health and help performance. Leafy greens like kale contain a wealth of vitamins that keep your body healthy and moving like vitamins A, B6, C, and K.  Whole wheat pasta in the right portions will provide you with the carbs you need to maximize muscle glycogen stores. If you want to run a 5 minute mile you need to train your body in other ways than just running to get into shape. Other exercises will not only help you run faster, but will help prevent injury and increase form.   Planks are a great way to strengthen your core, lower back, and shoulders; three areas that are important for a fast run. Hold planks for 45 seconds and do 3-5 reps. Kettlebell squats will work your glutes and leg muscles while also strengthening your core. Do 2-3 sets of 10-12 reps.  Do some yoga to help you improve flexibility, recover faster, and simply destress.

Summary:
Develop a training schedule. Eat a healthy diet. Work on your general fitness.
