You’ve decided that this year is the year. You’re ready for this. 2019 is behind you, and now you’ve got your full attention on your fitness goal. It’s the year of running.
Now, running isn’t a walk in the park (though there’s no shame if it’s currently just a fast shuffle), so it’s important that you warm-up and cool down appropriately. Look after your muscles and then they’ll look after you by reducing the likelihood of injury and helping you get out some extra speed/distance from your springy pins.
