Does anyone here have trouble focusing after a tough workout? Sometimes even a few days after? I used to do sprint training as part of my workout routine and also some weight lifting/machine. However, especially after especially tough sessions, it'd give me brain fog for the rest of the day and sometimes days after as well. Also sometimes I'd just be too sore to really concentrate. I'm currently doing a post grad degree which requires quite a lot of deep focused thinking and I've kind of stopped my exercise regiment as a result. Anyone else experienced this before and how did they deal with it?

Maybe a mineral deficiency after a lot of sweating? You could try with some good magnesium supplements (NOT magnesium oxide) or a spinach smoothie (dark green vegetables are rich in magnesium).

Would you take this before or after? I guess after, then how long after?

Any time after

Same happened to me, but I was at a point in my life where I didn't need to do a lot of deep thinking so I continued anyway, and after a few months my body had grown accustomed to it.

I can now push myself to my limit and will feel fine after 15 minutes.

I get something like I have a cold for a day after, headache, tiredness, sneezing, runny nose.

I get brain fog the same day too. I've not heard or read of this occuring normally. It's not bad enough to stop me driving but it is enough to stop all work.

I think it's fatigue basically and I've found that gradually increasing my fitness allows me to do more before this starts. But it's not listed as what fatigue is, especially the brain fog bit.

I Have a this too and it can feel like I'm broken for that, as it's the exact opposite of people who feel energized from exercise. I'm not in bad shape at all but even a 1hr walk takes some time to be back to where I can focus on work most of the time. No solution yet sadly, apart from doing it in the evening when you don't need to do anything afterwards.

Not sure if same, but I experienced similar to this when was not paying attention to heart rate and running hills. I thought the harder/faster the better but I was nearly maxing my heart rate for my age, and was exhausting me. I've felt much better now that I keep my heart rate in the 75-85% range during runs.

It could just be that you need a nap. I used to do a basic powerlifting routine in the morning, and my brain would get progressively slower and slower until noon when I took a nap.

It was like hitting the reset button and I was fine for the rest of the day.

Same here. No solution yet, other than lighter workouts or moving them in the evening. I rarely get the multiday effect too, but it takes multiday effort to get tbere and I vary rarely train hard enough.
