restore - git reset --hard HEAD^

Question

Unfortunately I did several times git reset --hard HEAD^ losing a quite big chunk of code in several files. Is there a way to restore those commits or in this case

Answer 1

Run git reset --hard HEAD@{1} if you just committed your code and you want to undo that.
