Chess course idea: health and fitness for competitive chess players

Hey Everyone,

This isn’t a sales pitch or anything like that, so please do not ban me.

As someone with around two decades of experience and self-study in the realms of both chess and health/fitness, I am considering creating an online course on the topic of health and fitness for chess players (and by extension, players of other competitive board and card games, or activities that require a lot of mental effort while being seated). There might also be the possibility of live group coaching, and/or one-on-one personalized coaching, etc. The goal is not only to help chess players improve their health and feel better, but to improve their results at the board through improving their health and fitness. Sometimes chess improvement comes from things other than studying the game itself.

I am just posting to see what you all think of this idea, and if you think there is any demand in the online marketplace for such a thing. I have searched a fair bit online, but cannot really find any program like this so far. Other, perhaps related, courses seem to exist, such as psychology for chess players (a branch of sports psychology, you could say).

Anyways, let me know what you think of this idea. Do you think people would be willing to buy low-ticket courses / group coaching on this? Could you imagine yourself investing in such a thing?

Thanks for your feedback!

Of course health and fitness is very important. But if you are thinking of making money at it, you are wasting your time.. All the information is already there, for free. And I don't mean on chess websites. Look for information on serious websites such as Harvard Health, for diets designed ti preserve and enhance cognitive abilities.

Nimzovich credited the health and fitness program for his victory at the Carlsbad 1929 tournament.
Fischer played tennis to play better chess.
Korchnoi, Geller, and Petrosian went swimming during the Candidates' tournament 1962.

Just speaking for me (passionate and bad hobby player of chess with some serious efforts in composing and analysis of chess problems with academic and professional knowledge in computer science) fitness, nutrition etc. are only relevant for some 24 hours online tournaments like Lichess Guinness World Record, Lichess Social Chess Day etc. and whatever the topic will be in July next year.
There is a German book on two 24-hour blindfold simuls by FM Marc Lang (title "Schauspiel des Geistes", Editor GM Raj Tischbierek) with some insights on nutrition in 24 hour chess given by an anonymous internet amateur but "anecdotically" confirmed by the practice of Marc Lang who successfully used the tips of the anonymous amateur (much drink, low carb [or physical exercise going with the carb because otherwise the carbs are not processed usefully, practical possibly only for online tournaments], some balanced portions of fruit...).
There is a film on Fischer telling that he specifically worked on a tough handshake besides standard fitness
(Bobby Fischer Against the World).

For a course, maybe a DVD or voucher version would be good so that physical sales are possible at chess tournaments.
Group coaching may be good for already existing chess teams.
I doubt many chess players are willing to attend group coaching outside of existing chess teams.

Health and nutrition is most relevant for multiple day over the board tournaments in classical time control that require hours of deep concentration.
Here are some good tips:

I think the best sport to take up is parkour: so that one can arrive on time when in a pinch, as well as knowing how to escape a difficult position...

In case people are unaware, Nimzowitsch's 'My System' is not named after chess but the fitness program of exercises that he followed.
