I really like the color pallete that nike has going on. I want a clean but bold font that really stands out. It needs to be eye catching, and cannot blend into the shirt. Contrast is big on this one.
I would like the shirt to be interchangeable between black and white.
This is for the bodybuilding community, so if your going to use some silhouette by any chance, it has to be someone big, freakishly big. No average sized muscles. Were talking about Mr Olympia Big. No need for silhouettes though, just letting you know if you do use one.I added two silhouettes if you do want to use one of them in your design. Again its not required.
This should be very modern, again somewhat like the nike shirts.
I do like when words have words in them to create that word, if you know what I mean, however this is also not required, just something you may put into consideration if your creative enough to make that work.
I added vectors of both the logos for black and white.
If you cant get the logo to fit right, just the text will do. If you find a unique was to add the logo image that would be great.
Update: Added silhouettes of bodybuilders that may be used. These are the size of the guys I would want to see if you had made your own silhouette. Again, its not required to use one.
Here is a great example of how someone incorporated the text into an object such as the grass on the bottom to make the plain quote stand out to others in a stylish manner:
Clean modern shirt here is nice:

An example of good contrast on the shirt. (Left shirt)
