@panozaa_allbet I took up running last March. I got lots of migraines. Then I found out that I can predict if I will get an exercise migraine based on how long my heart rate is in my zone 5 during my workout. I have a polar h10, and I can look at the HR graph and tell right away based on how long my HR is in the red, if I will get a migraine.
Anway, I found that I can still do cardio, but I just can't push too hard for too long. So I jogged/walked until jogging continuously with my heart rate in zone 2 was possible. Now, I have been able to add some hills and distance, but if I see my heart rate get too high for more than a minute or two, I slow down or walk.
This can be applied, I'm sure, to any exercise.
