So I am quite lucky and live very close to work so there are weeks when I do walk to work which takes me about 15-20 minuets so when I walk to and from work I will listen to some Spanish on my commute.
( not sure if its helping me or not but input is still input )
Yesterday I went to the doctors was 30 min drive there and back the whole time I was listening to my Spanish so before 9 oclock I had already completed my target of 1 hour of listening.
what I would advise as your level is the lesson you complete, save the audio and just have them on play or repeat when you are commuting too and from work.
