The Murph workout is among the world’s most famous, and toughest, fitness tests. It was created to celebrate the legacy of US Navy SEAL Lieutenant Michael Murphy, and it's completed by thousands of people around the world each Memorial Day under the banner of the 'Murph Challenge'.
The workout is a devilish 600-rep test comprising push-ups, pull-ups, and squats, all sandwiched between a couple of one-mile runs – and if that's not challenging enough, to do it to the letter you also need to wear a weighted vest throughout.
