Winter isn't for a few more months, but this is good to keep in mind for when it's approaching.
Crazy Russian Hacker is a YouTuber who shows you all kinds of interesting tricks for the outdoors. In this video, he shows you the right way to chop wood. It's a heck of a lot less work than you're probably doing now.
The trick is to lay the log perpendicular to and on top of another log. Then swing the axe at the middle of the log and it'll split in two. There's been lots of viral videos of people easily chopping wood using things like chains or bike tires. But this has to be the hands down, easiest method I've ever seen. It also seems like it's safer!
Later in the video, he'll explain why splitting logs vertically isn't a good idea. Watch below.
