Why does exercise get easier the more we do it?

Why does exercise get easier?

So you’ve started your workout program, you’ve been motivated and consistent…and you’re actually seeing progress!!

You’re getting faster, stronger and you can do more. But what is actually happening?

When you put your body under physical stress from exercise regularly, changes occur within your body’s physiology to enable you to respond to the stress better and maintain homeostasis or balance. This is known as physiological adaptation.

Here are just a few of the changes that are seen:

  • Heart muscle gets bigger and stronger

  • Heart can pump out more blood to the rest of the body

  • Reduced resting heart rate and blood pressure

  • Increased capillaries and gas (oxygen and carbon dioxide) exchange

  • Increased lung volumes and ventilation

  • Increased size and number of muscle fibres

  • Increased motor units recruited

  • Better intramuscular coordination

  • Increased size and number of mitochondria (the powerhouse of cells)

All these changes mean that your heart works more efficiently and can deliver more blood to your muscles.

Your lungs can take in and breathe out more air and also have the more capacity to exchange oxygen for carbon dioxide better. Your muscles become bigger but also contract more effectively.

And you can make it generate more quickly.

Harder. Better. Faster. Stronger.
