About this font family
Muscle came from the original sketches for Sneakers. At the time my concentration with Sneakers was to create a curvier, chunkier display. I left Muscle behind, thinking it was too masculine.
Rather than discard those original sketches, I decided to make it even heavier, reduced the total number of weights, create a function small cap system that when integrated with the lowercase makes a great biform component for short display settings.
