What does 'on the hoof' actually mean?
If you do something on the hoof, you do it while doing something else. It's a form of multitasking.
Example: I'm going to learn my English on the hoof today, as I've got to get some exercise and have planned on a 2O min run for lunch.
You see, you can actually learn English while you're walking, running or even driving with the podcasts here.
Simply download the audio and put on your handsfree or Bluetooth and you're away. Couldn't be easier.
