@jg_lrd To be fair I always hated running, HIIT and circuit type of workouts
I was a gymnast back in the day so had more than my fair share of running, but I am not built like a runner at all. I am more of a power and strength type,so when my coach said that the only cardio he ever expects me dto do is daily steps and long walks, I couldn’t have been happier. My resting heart rate is 50, blood pressure low, weight has always been in the normal BMI range, now on the lower side. But my LDL cholesterol has been always high despite almost never having anything fried, never using oil for cooking, all over very low fat comsumption. Well, the fish oil took care of that. My hunch is that there is a strong correlation between migraines and high LDL.
Edit cuz forgot about the heart rate: I do wear a smart watch so I can monitor my heart rate and I often do when I am doing a particularly heavy workout (think attempting a deadlift or leg press PR). However, even if my heart rate goes way up, it causes no problems as long as I take appropriate rest after it. Hence the 3-5 minutes rest between sets when I really go for it. I just don’t like running so no matter what I do, it never feels right. That said, because I found running and jogging boring, I did intervals (alternating springting and jogging) and that didn’t cause me migraines, I think also because of the “rest” between sprints. So you might be onto something with monitoring heart rate.
