I designed my logo with the idea of having it look great on shirts, gym bags, etc. Something that your gym goers would love to get their hands on! So I came up with #68, and then I also dropped in a distressed/grunge layer to give shirts and other things a really cool vintage look: #67.
I look forward to hearing what you think!
Also, I will be happy to provide revisions as needed, so that we can get this exactly how you want it.
Thanks!
