Thank you for the great post on LSD Michelle – really summed it up well…

Work Hard/Don’t complain about WOD’s/Take care of your hands/Roll out your body/Show up ready to breath fire and build muscle/Stuff your face with quality food/Wash it down with H20/ICE down your sore spots/Read Blog posts and take notes/Implement what you learn/Rest/Repeat

…And then someday soon you will earn your spear and your knife so that you can run with the big dogs…

We do train all three metabolic pathways at Invictus (I think you meant Phosphagen, Glycolitic and Oxidative). The issue is how OFTEN you train each of the three pathways. Spending excessive time in the oxidative pathways is, in my opinion, less beneficial than focusing the majority (somewhere around 70-80%) in the phosphagen and glycolitic pathways. No doubt, training in ONLY the phosphagen and glycolitic pathways must be reserved for specialists who make a living or hobby out of competing in those two pathways.

I am not sure we would agree on what constitutes a “Met-Con Bomb.” Give yesterday’s workout a shot – 60 seconds of work followed by a 3 minute rest. Push as hard as you can on that workout and compare that with how you felt on Kelly. Typically, the “met-con bombs” permit higher intensity, while Kelly tends to slow most folks down enough to make it somewhat less nauseating.

And for those with experience in pushing the limits of their work capacity, ask which is more mentally challenging, 800 meter repeats with at least 3 minutes of rest between runs, or a 5k or 10k – I’ll take the 5k or 10k any day.

In hot regions like humanity’s beginnings in Africa, man’s adavantage over many animals is his evaporative cooling system. Antelope and other creatures lack the ability to sweat so men would separate an animal from the herd and keep it on the move until it overheated.

As humans spread to other areas with colder climates, it makes sense that other hunting methods would need to be employed since animals overheating was likely of little concern. This is where your short bursts of high-intensity exercise came in handy.

Either method is accurate if you want to approximate ancient human “training” methodologies, you just get a lot more bang for your buck with shorter, higher-intensity training methods, which is why we stick to them. Check out my post on the fat-burning zone myth, which also addresses how we use fat for fuel in long aerobic efforts and more glycogen in our short anaerobic events.
