You could, but I only recommended it since you said audio/video.. the "music" on spinervals isn't so great, and it might get annoying having to listen for the gear change cues (which have a visual display on the videos). For just audio, there must be a better alternative, i.e. make a good playlist of your favourite upbeat/downbeat songs for interval training. I think there was a thread in the training/nutrition forum with some recommended playlists, but I can't seem to find it.
