Blast Fat (and Build a Bigger Chest) with this OCR-Inspired Workout

All you need is some space to run


Andrew Tracey |

Combining explosive bodyweight bouts with running intervals is an absolute panacea when it comes to training for any obstacle course race (OCR). But even if you’re not a Tough Mudder addict or Spartan Race hopeful, this type of training still has huge benefits: it can build a strong cardiovascular system, a powerful strength-to-weight ratio and can melt calories faster than snowballs in the Sahara.

Requiring nothing but your bodyweight, put this protocol to good use outdoors in the winter and you’ll also get an immune-boosting dopamine hit that builds mental strength to boot.

Measure roughly a 200m distance from your home (or wherever you’re going to tackle the workout), creating a 400m loop. Start with a round of the below bodyweight circuit, ticking off all three movements as quickly as possible, but keeping your form sharp. Next, hit the road and complete one 400m lap. Pace yourself, but move at a decent clip, as this is a run and not a jog.

Repeat the circuit/run combination a total of eight times, timing yourself. Work towards adding an additional round or two into the same time frame as your fitness increases.
