You are very talented and have lots of great ideas. #64 is still my favorite of the group. It really pops out. I'm just not sure how it will look across all mediums (web, social media, t-shirts, etc..). And not sure it really communicates health and fitness. But still one of my overall favorites so far.
Hi perpetualfitness, Thank You. IMHO Many fitness centers currently using the swoosh or humanoid shapes as their logos. I think these kind of design quite popular among gym/fitness community :) I'll keep Improving my design as an option for you to consider.
