Chia Seeds
Chia is one of nature's highest plant-based sources of complete protein. Some proteins, like peanut butter or beans are incomplete, meaning you have to combine them with other foods to get the full nutritional benefit. Chia's protein is fully complete and works to raise your energy levels upon consumption.
This food, too, has history behind it. This little, whole grain is an ancient health food that was used by the Aztecs and Mayans as a main energy source, according to Fox News.
Add to smoothies, cereals or in baked goods to give that extra boost you need to maximize your exercise routine.
Lean Beef
Learn from Popeye's example—iron is key to a healthy body. Though he noshed on spinach to obtain iron, lean beef can have the similar effect on strength and endurance. Iron is a crucial nutrient for endurance athletes because a deficiency leads to fatigue. Additionally, lean beef is a great protein source. Elk, bison and less-fat beef are low-fat and high-iron types of protein.
Sports Drinks
Though sports drinks get a bad rap sometimes, they actually can really benefit your overall stamina and energy levels during long periods of exercise. Sports drinks can rehydrate runners while delivering carbohydrates and electrolytes. Look for sports drinks with 4 to 6 percent carbs/electrolytes. Any more than that will leave you sluggish and full of too many sugars.
