Brisk walk at 8km/h

Another brisk walking training. This time, I added the hip twisting motion to my usual fitness walking style. I have tried several times to train the hip twisting motion during training but usually cannot last more than a few hundred meters. But this time, I am able to add the hip twisting motion for almost the whole 6.6km though in some part, the hip is not twisted far enough.



Although my stride is longer with the tip twisting, I have difficulty in combining it with toe pushing. And also the cadence is slightly slower. At the end, still 8km/h. I need more practice and later incorporate the toe pushing into it and speed up the cadence. But getting the posture correct is the first step.

Yesterday, my heart rate monitor is missing beat (recording heart rate that is too low). I check the battery on the chest strap today and seems that the battery is running low (2.7V instead of normal 3V). I have replaced the battery, but as you can see from the graph, in the first 1km, the HRM go haywire and register >220bpm!! But then, it goes back to normal. Strange??? Battery voltage too high?
