Why 10
You have 60 - day usage.
The 10 is based around a challenge system.
(so you now can put yourself in an athletes shoe and workout like one, or train like a pro with Team 6 Training: outdoor fitness & outdoor training program.)
You can even let your Bestest buddy! use your valid sessions
They can even stand on the side and record your scoring so that you can get those numbers. T&c applies
