I found that going to the gym 5 days a week and spending 15-20 minutes on the treadmill, max slope@15% starting at 5.5 kph increasing to 6.5 kph (a brisk walking pace) by 10 minutes would to start generate a sweat after 8-10 minutes.
Going to the AME a hour after would reduce the bp by 10 points systolic. Dilating the coronary arteries!
Caution: for those not in the first flush of youth, a gentle build up to this regime is probably best.
