Made it again today! Running late again, though, so I just did the treadmill again.

Including the warmup: 5 minute warmup; 20 minutes alternating jogging/walking in two minute intervals; 5 minute cooldown. Again, I did the last jog cycle for a full four minutes.

1.76 miles, about 150 calories.

Stretched afterwards.

I am already noticing a difference in my stamina through my heart rate and breathing. This time, my heart rate did not get above 159, except for after the final four minute jog when it was up to 164. At the end of the other jog sessions it was somewhere in the high 150s. During each two minute walking period it decreased rapidly to the neighbourhood of 130 - down into the 120s several times, and down to about 133 near the end. By the time I finished the 5 minute cooldown, it was about 120.

Also, 40 situps first thing this morning.
