Thanks for offering some ideas for my logo. A couple of comments:
I think I'd like to see initial caps on the words Greatest and Age. Lower case is too diminutive. I want the logo to make a more positive and stronger statement about the population who will come to my studio. As people age they start to feel like they are loosing power. I want them to feel empowered when they train with me.
the G figure doesn't work for me. I feel it doesn't add to the power of the statement. Figures working together does have some meaning here. Or somehow symbolizing community empowerment would be great. It has to appeal to both genders, so angles are not out of the question.
