I had had that random thought on Sunday night but didn't do it. Then yesterday I was inspired by my sister who old me that she had slept in her workout clothes on Sunday night in order to minimize excuses to getting up early.
So I tried it last night.
Other than waking up at midnight, 2:30, and 4:20, there wasn't much difference.
Unfortunately, that's kind of a big difference... So I'm not sure if I'll do it again tonight or not.
But, I did finally wake up - and GET up early!
And here are the fruits of my labors (not bad for being done before 6 in the morning, right?) -
this was during my three minutes of cooling down (rounding out the 45 minutes).
the other 42 minutes were split 50/50 between running 5 mph at a 4% decline (totally works the abs)
and walking 3.5 mph at a 15% incline (with 1 minute of 40% incline thrown in there just for fun).
