With this in mind, lets put that to the test shall we.
If you can, get outside and head out to my playground in the woods. Get off of the path (look for a deer track) and get a jog in. If you meet an obstacle then jump it, climb it, crawl under it. I want you to try and get a good 45 minutes of exploring in. Be as quiet as you can as you do it - when you go into 'stalk mode' your core tightens, your breathing is more controlled and the effort to become lighter on your feet intensifies the workout on your legs.
If you cant make it to the great outdoors then create your own path - at the office, in the gym, at home. Create as many obstacles during the day that you have to climb over, jump off, crawl under - add some sit-ups, press ups and squats just to keep it real -
Probably best that you print this page off though...
...just in case the boss questions what the heck you're up to - just tell them 'Rod made me' and get him to join in!
