Endurance is another aspect of physical activity that anyone would love to increase. After all, it’s fabulous to exercise more without feeling like a total wreck—both during your workout and when you wake up the next day. So how can you boost your endurance?

Glucose can’t enter your muscles without insulin, even though it’s your body’s primary source of energy. In other words, you can eat all the carbs in the world, but if you don’t have enough insulin… Your muscles won’t get any of that. Sorry, mate, no gains for you.
Nitric oxide (NO) is a messenger molecule that your body uses to relax and widen up its blood vessels, enhancing blood supply to where blood is needed.

More blood means more oxygen, more energy, and more nutrients to work at peak performance.
