I missed a lunch bolus last week and 2 hours after eating I was at 354 mg/dl. I was at work, so I couldn't hop on a treadmill, but I injected intramuscularly and high revved my left arm in a 4-minute set of tabata timed intervals.

I was down to 110 mg/dl in 1.5 hours and I estimate that the Novolog was all used up in about 2.5 hours.
