Here's What Really Happens To Your Body On A Morning Run

The first ten minutes are lying to you, and here's why.

If the first few minutes of every run feel awful, you're not unfit, your body just hasn't caught up yet.

Early on your heart, lungs and muscles are scrambling to switch gears, which is why it feels so rough.

Push past that opening stretch and something clicks. Breathing steadies and your legs suddenly feel light.

So don't quit at minute five. The good part is waiting just around the corner.
