I love your logo, really nice. I am really struggling to decide between yours and one other logo ATM. It's up to you if you want to bother changing anything at this late stage as you are currently in my top 5 anyway. If you did want to change anything, I think I like the Fitter Firmer Faster to be more of a bold font but still a smaller sized font than the company name. The colours are good. Thanks for your work :)
