Trainers revisited

See screenshot for an (almost) full page, except for the footer. Since it's a responsive design, there are some slight pixel/layout 'misbehavings' due to the fact browsers render percentages differently. For instance, the 4 different workouts should be 1 more pixel to the right here. If I do it correctly (this screenshot was taken in Chrome), Firefox/Gecko breaks up the grid and puts the last workout on the next line. It's a work in progress, but what a fun project and client to work for!
