Zest magazine has launched its 8-week summer body challenge, inviting readers to document their progress in the Zest Reader Blogs.  Readers have various reasons for taking up the challenge, from shaping up for a summer wedding to reclaiming their pre-baby figure, training for a triathlon to a 10k run.

Bloggers can log their progress, upload images and even seek advice.
