Relativity.

16 minutes is nothing. Think about all the things you might do in 16 minutes without even giving it a thought. 16 minutes left in a work day? Nothing. A 16 minute bike ride? Not even worth getting suited up for. A 16 minute nap? Nice, but really not going to make a dent in any fatigue. A 16 minute dog walk? Otto is suggesting that is completely worthless. A friend 16 minutes late to an outing? You probably wouldn't even start to get mad.

But 16 minutes of crossfit? Lord, that's a different story entirely. 16 minutes of crossfit can be deadly. 16 minutes of crossfit can leave you unable to ride your bike to work or run for days. 16 minutes of crossfit can make you completely unable to type (something I am experiencing right at the moment). 16 minutes of cross can chew you up and spit you out.

Now, think about 20 seconds. When you think of 20 seconds of anything it barely even computes.

Finally, combine 20 seconds and 16 minutes and crossfit. Today we did a 'Tabata' workout. Tabata is 20 seconds of work followed by 10 seconds of rest. 20 seconds of work? That doesn't sound too bad. Shoot, one might even argue that sounds easy. We did four exercises, 4 minutes of 20 seconds on/10 seconds rest. We even got 3 minutes of rest between each excercise. And I'm here to tell you that even when your brain is screaming '20 seconds is nothing!', at 10 seconds to go, you body is screaming 'must stop now!'

And now a call out, I need ideas for good workout music. The music during out workout today was some of the worst, I don't even know what 70s rock combined with bad techno. So I have been challenged to do better. Any ideas???
