Looking for advice or other people's experience in this area. I've started running again, as my health is improving. I thought that I would be able to start out jogging and keep my heart rate down, however as is often the case I overdid things and my heart rate shot up post exercise. Almost a week later and my lymph nodes are no longer swollen and my resting heart rate is normal. The treadmill I use has a heart rate monitor, but it's basically useless. Measuring heart rate manually, I definitely got above 80% of anaerobic threshold. Has anyone else managed to get into careful exercise? I get really jealous when I see runners out and about, I loved running, and I know that I should be careful, but it's like a drug. I haven't had a drop of alcohol for months, but if someone offered me a PEM free night of drinking or running, I'd take the run.
