Hi, Thanks for the info, I am also on Beta Blockers as I have arterial fibula ion(Irregular Heart Rate)
I am 65, and cant get my heart rate much above 85 on the treadmill, even with effort. My BP has also improved over time and I have reduced medication
I go to Gym 4 days a week
I think any exercise is very good, and am still getting the results as I consider myself quite fit for my age.
Keep it up Nicholas, Loosing weight, I think try the Low carb route, lots on info on the site, I've lost over 25 Kilos in the last 18 months, and my latest HbA1c is 28 (4.7%)
Life is good !
