I need an infographic | Freelancer

I need an application icon.

The logo we need is about a street workout iphone application.
Mainly the idea is to represent a athlete man in a difficult position upon a bar.
The logo should reflect the underground side of extreme sports.
Choose some powerful "action style" colors that fit the context.
The side of the provided PSD should be of 1024x1024, but we should take into account that the logo will be small once put on a device scale.
