@ 139 - great idea with the logo. bent barbell and a z. very cool idea.
Try the Zigzag with all one colour. Shrink the I in Zig so its the same size as the gzag. (keep the first Z the size it is).
Shrink the logo just slightly or increase the font so the font and logo are level.
Also trial this logo with the following 3 colours: bright blue and bright green. if so then trial as follows: Keep the bits you currently have green. The current black is turned to the bright blue colour (even on the logo). I get stuck to whether the fitness stays black or you turn it blue??? and then the tag line???? goes green if fitness goes blue??? you can figure that bit out. Your the creative one here.
Lets see how you go. Great work. Like it a lot.
