Placeintheground’s ratings are completely biased, nonscientific, and are purely my personal view of a particular activity, product or service. Three classifications are used; fun, motivation, and fitness, and are out of a total of 5 ticks. 1 tick is very poor, 5 ticks is about the best you can get.
Fun factor: 
The most straightforward classification. Is it fun? The more ticks the better!
Fitness factor:
A bit more complex and open to a variety of opinions. This is a quick take, but not necessarily popular, opinion on how good this activity is for your body as a whole unit.
Motivation factor:
The most subjective rating. Certain people will find different activities & ways of thinking more or less motivating, please feel free to comment and tell me what score you would have given!
