#89 , here is my concept and play on making people figure out its " golds gym " brand right away with the ease of reading of " 45 " , where the number " 5 " inner line curves is bending with the same curve of the bench to create the right balance and help make " 45 " easily read and the figure filled inside and on the outside of it to stand out strong and retain the overall balance of the logo / icon mark here.
Also you can use alone as in #92, #98 and #99 , as you can see, the " 45 " is easily read and the golds gym statue is standing strong and clear in it as well.
