UI Design for a fitness app

For this week's design challenge I decided to polish a previous project and experiment with some UI design. This project was a mock project from my time at Flatiron School, in which we designed a fitness app for the YMCA (the YMCA is not affiliated with this project in any way). This fitness app was focused on social interactivity, so we built an app that allows users to search and build their own workouts, post it to a social page, and send fitness challenges to their friends.
