What series would motivate you during exercise?

[Marcia]

I am an audio book addict. I need help finding a new series - preferably one to help motivate me when exercising. Something with kick butt heroines, training & fight sequences maybe??? - The Fever Series or Night Huntress series would be perfect - if had I not gone through them multiple times already:-) Any Suggestions?

Maybe the hollows series, or Dorina Basarab series.

If they are available, perhaps Mercy Thompson and Alpha & Omega series and/or Kate Daniels.
