Unable to Push Changes to Remote - Error Message

Hi all, I am struggling to push changes from a one repository to another on the local machine. I have setup my test scenario as follows:

1. Created a git project called 'git-testing' and initialised the git repository.
2. Added a blank file 'index.html' and committed it.
3. Cloned the repository to a sibling project folder called 'git-testing-clone'
4. Setup 'git-testing-clone' as a remote repository to 'git-testing' called 'clone'
5. Confirmed the remote has been setup by using 'git ls-remote clone'
6. Made changes to 'index.html' inside 'git-testing'
7. Commit my changes inside 'git-testing'

Now when I try to push my changes to clone, by doing the following:

git push clone master

I get the following error: C:\Users\James\Dropbox\WEB\git-testing>git push clone master Counting objects: 3, done. Delta compression using up to 8 threads. Compressing objects: 100% (2/2), done. Writing objects: 100% (3/3), 334 bytes | 0 bytes/s, done.

To ../git-testing-clone ! [remote rejected] master -> master (branch is currently checked out) error: failed to push some refs to '../git-testing-clone'

I have done some Googling but I am struggling to understand the responses people are giving. Would be great if somebody could help me understand what may be going wrong.

Additionally, I have installed GIT to work inside the Windows console as I had some difficulties with backspace misbehaving inside the MINGW64 console that seems to come as default.

Many Thanks
