End of Week 9 of '90 day transformation challenge'

Diet and walking was on track during the past week, resulting in a -1.3 kg change in weight for the week, and a -1.3% reduction in body fat percentage. The diet and walking resulted in an average daily caloric deficit (compared to estimated BMR) of -1,206 kcals/day on average during the past week. The charts of weight loss per week vs. average daily caloric deficit show an almost perfect match with the predicted loss of 1kg/wk for a 1,000 kcals/day (7,000 kcals/wk) deficit for the weeks where my diet was 'ongoing'. There was a higher rate of weight loss during the first weeks, and the week immediately after I had paused my diet and exercise regime due to my BPV episodes. The higher rate of weight loss can be explained by the usual 'water weight' loss that usually occurs when a diet commences (and overall bulk of food consumption decreases).

I still haven't resumed going to the gym for weight training sessions yet -- my new Waterrower arrived on Tuesday, so I did rowing sessions on Wed, Thu, and Sun instead of going to the gym. This week I'll try to doing rowing on the 'rest' days when I don't go to the gym for weight training. While indoor rowing is a good 'full body' workout, it is only 'bodyweight' and is more limited by aerobic capacity than muscle exhaustion. So far I have only managed to do one or two 6 minute sessions on the rower, covering 1.3km in about 260 seconds. Despite 'only' being 1.3 km, this pace is still about 30% slower than the WR pace for the 2km event for the 60-65yo age male open category, so I'll need to first improve my aerobic fitness and endurance to be able to row 2km at a decent stroke rate, and then (hopefully) improve my technique and strength to slowly improve my time for the 2km indoor row. The rowing can be quite strenuous, so I'll start wearing my fitbit watch while rowing so I can keep an eye on my maximum heart rate.
