Potassium is an electrolyte that plays an important role in muscle contractions and nerve transmissions. It’s also involved in storing carbohydrates as fuel for exercise. A deficiency of this mineral can contribute to muscle weakness and even cramping. So what types of food should you include in your pre-workout meal to make sure you’re ready for a session of heavy lifts?

According to a blog post on the Times-Picayune’s nola.com site, bananas are an abundant source of potassium and carbohydrate energy. Cantaloupe is another good source of potassium, and an 8 ounce serving contains about half the calories of a typical 120 calorie banana. Then you have protein food sources including fish scallops and pork loin which all provide between 450 and 550 mg of potassium.

True Strength Moment: Vary your nutrients for best results, and be sure to keep up with hydration. Losing as little as 2% of your body weight through fluids can contribute to a 10% decrease in exercise performance.
