Borg scale

The Borg Scale is a way of measuring how hard someone is working out or exercising. It’s named after a person named Gunnar Borg who invented the scale. The scale goes from 6 to 20 and each number means how hard you feel like you’re working out.

For example:

- If you’re sitting down doing nothing, you’re at a level 6. That means you’re not working out at all.
- If you’re walking slowly, you might be at a level 10. That means you’re starting to feel like you’re working out a little bit.
- If you’re running really fast and you can hardly keep going, you might be at a level 20. That means you’re working out really hard!

The Borg Scale helps people figure out how hard they should be exercising. It’s important to choose the right level for your body so you don’t get too tired or hurt yourself. So if you’re feeling like you’re working out at a level 14, you might want to slow down a little bit and go to a level 12 instead.
