I am a 71 year old male in reasonably good health except for high blood pressure. I'm not a couch potato but I don't have an exercise routine. My doctor has recommended daily exercise to go with the medications I take and I would like to acquire some sort of device that would be appropriate for my circumstances. I have a stationary bike and perhaps a good daily regimen on its use would satisfy my needs. I'd appreciate any opinions from some of you experts on the matter.
