You could try programming katas or very simple leet code problems. After completing 10 or 15 of them in your favorite language, try again. It should go faster and the quality of your code should improve a bit (unless you are already at a fairly high level). You can then move to a language you know less well or to one you would like to learn. Sadly, at least for me, even relatively routine programming tasks take more time than drills like shadowboxing or speed bag work, so finding a close equivalent is hard.
