My mental endurance sucks!

[Su Lin]

Ok so these days my fitness level is getting pretty good but my mental endurance isn't great at all. On a Monday I have 1 hours mma with an hours break then 1 1/2 hours kung fu. Both classes have sparring, plus I'm taking on new techniques in mma, but by the time it comes to kung fu I struggle to even remember my basic forms! I have my black sash grading coming up in October, basically it's a weekends course then the syllabus grading at 5pm-8pm on the Sunday night. If I carry on like this I'll be a wreck mentally

Anyone got any tips on increasing mental endurance or is it something that will come along eventually?

Do them on different days.

I can't as those are the only class options I have Anyway I want to be able to train for longer so it's irrelevant what I do when really.

From your original post it seems the issue is retaining information, not mental endurance.

If you're talking about forgetting forms you have known for a while then it's probably just fatigue. As your endurance gets better you won't have as much trouble. You might feel ok doing both but that doesn't mean it's not taxing you. Pluss you trying to remember newly learned material from the first class so it's dividing your attention.

Make sure you're getting enough sleep.

Sleep deprivation causes mental fatigue and retention problems.
