This became more of an issue when I got older. I used to run in the evenings and get away with it. Now in my 40s, I have to run in the morning. If I run at night, I wake up feeling tired and not well rested.
I don't run that often anymore, maybe twice a month, but I can only do it in the afternoon or evening. If I go in the morning, I feel very tired so I really have to force myself to keep going, and then after 15-20 minutes, my heart rate settles at close to 190bpm (compared to ~175 in the evening) which to my understanding is way too high for someone in their early 40s.
Personally I need 10-20 hours of real sport a week to function really well, which seems to put me in some very high percentiles on HN. I need so much sport that I barely have time to do anything besides work and exercise, which means I don't do many non-athletic hobbies anymore.
Do you have a specialized wrestling gym or something like that near you? I've never heard of such in my area so I'm intrigued.
