A belief and approach to exercise, diet and lifestyle, where to 'Smash It Out' is to put your best foot forward, give 100% effort and have no reservations that you could have done more.

To complete a hard-core, assassin-style workout at the gym or outdoors.

To complete a hard-core spy training style session.

To attack and complete an exercise or circuit in an animalistic way, no holds barred, 100% effort!
Come on guys, let's Smash It Out together!

Really go hard on good eating this week - Smash It Out!
