Love love love the colors. This is far and away my favorite use of colors. I think the central star is a bit much. #30 is too macho and sinister for me.
See my comments on #8. I wonder how this might look with a hexagon shape like a stop sign? Also, I don't want this to look too much like the Gold's Gym logo (which is awesome). Thinking out loud, maybe a man in side profile doing a dumbbell curl. Kinda like the "H" too: don't know which way I might prefer.
