This logo design really speaks for himself and for this business. Take a time and think about how it would be good if we could go in a gym whatever we want? How magnificent this business solution is? And when you have such a business, you really must to do a good design. Really, for this business you can do a bunch of creative designs and every would be excellent. But in my case, I decided to go with a typography solution. Also I managed to make such a good design for middle letter "N". Upper part of letter "N" is like a sun for day, and lower part is like a moon for night. And everything fits perfectly with a rest of design. Really clever design, but also appropriate for fitness.
