I use a HIIT spin class mp3 that I downloaded from Amazon. It's great for me because I can still take a spin class at my gym anytime. I don't have to worry about making it to a class on time. I really like Cycle Coach by Rachel Buschert Vaziralli . She is motivational and each set is different.
If we had to vote on an anthem for joggers I would nominate Runner's High by rapper Stic Man.
If you like the song then you might also enjoy his whole Workout mixtape. It serves as my motivation to give it my all on those days I want to take it easy.
