HillerCast 006 : Fitness as a....Video Game?

My attempt at trying to explain how training solo is as good, if not beter than, training with others. 

This was prompted by a text message I recieved about motivation lacking in a solo training enviornment, and how I have alway looked at my own solo training. 

Examples include : those who are begginers, well versed in fitness, and competitive athletes.
