I have started at the gym, after a long layoff. A recent blood test showed a level of 88 which I know is high. Over the past three weeks I have been walking for at least 30 minutes every day on the treadmill at 3.5% slope and 6.5km/h which is as much as I can manage at present. My effort level is around 72% and I am managing to keep my heart rate between 140 and 145 for between 15 and 30 minutes each time (the latter was on a 45 minute session). I am aged 66 and weigh 101lbs. What effect is this likely to have had on my levels, given that so much more blood is being pushed around my pancreas? I have another blood test next week and would really like to see my level fall, but am not sure if I am doing enough. I have also started being more strict on my diet, which I hope will also help. Any guidance or advice welcome!
