My plank exercise is going better. I was getting pain in my arm, so I decided to try with a pillow under my arms and I got much better results: 30 seconds!

FBG today 89.

Walk this morning:
51 active minutes with 52 minutes in the cardio zone with 47 in the fat burn zone, only 1 minute in peak. I know for certain that I was walking at a faster pace, so my heart must be getting stronger, thus keeping me out of peak zone. In other words, the heart rate which is "peak" is getting higher.
