Overall the logo should be fairly simple as you can see by the current design. The words "built" and "fit" should be different so you can actually differentiate both words (like two different colors).
We thought about having a symbol or icon between the words "built" and "fit" as one possibility. That symbol would relate to either being fit or having a ripped/strong physique.
While we do not mind the current logo, we are looking to add a symbol/icon of some sort for branding purposes.
We would like everything on the same line.
Keep in mind that the logo will be used for promo materials, t-shirts, print, and other items.
The logo will be on a white background but be sure to also show how it will look like on a dark background.
You can show the tagline as an option:
Build Muscle and Get Fit
