You don't exercise because you have energy, you exercise because it gives you energy
This is a conclusion you’ve come to Empirically. It’s in the literature, but it’s in real life, too.
Exercise takes energy to do, but it returns a higher baseline of energy. You may end a workout tired, but mentally you’re more alert. You bring on endorphins that last with you for hours. Your minute-to-minute energy levels are improved when your day-to-day routine includes some level of intentional physical exertions.
Exercise also helps regulate your mental and emotional well-being as well. You can complete the Stress Response Cycle. You can feel secure in knowing you’re doing what you can to increase your healthspan.
