Eli5: Why exactly does regular exercise give you more energy?

164 views

My workout routine has always been erratic. I work out regularly for 6 weeks, then stop for a few, then start again. It’s a cycle.

But without a doubt, the weeks where I regularly workout, are the weeks where I have much more energy during the day.

Why exactly is this? It seems like it would be the total opposite. If you’re regularly breaking down your muscles, it would make sense that you would be MORE tired during the day. But I’ve noticed that it’s the exact opposite.

Why is this?

When you work out, you push blood through the veins much harder and faster. Every subsystem in your body will suddenly get the nutrients, oxygen and energy they were waiting for, and they will get rid of waste like dead cells and co2 as well.
