"According to researchers at the University of Illinois at Chicago and Kaiser Permanente, white men in particular who exercise at high intensities are 86 per cent more likely to develop plaque buildup in their arteries."
I for one get your question and do not think it is dumb. You can overdo exercise. But I would be more intrigued to see what diets these high-intensity exercisers were following. If you know elite athletes, not just body-builders, it can be very illuminating to hear their takes on long-term healthy nutrition as opposed to mainly building muscle. My bike fitter, a former triathlete ranked fifth in his country at one point, told me to cut out refined sugar but eat more fat, for instance. Never read that in a fitness magazine. I went back to eating skin-on chicken, whole fat milk, real butter, frying potatoes in chicken fat etc. every day and lost 10 kg in a year with very moderate (basically lazy) exercise like biking once or twice a week for a couple of hours.

"Cutting out refined sugar" THIS!! That sh!t is poison, but so bloody difficult to avoid. Sweeteners are everywhere..

I missed this topic. Wish I had found it earlier.


I used to coach Crossfit for 7 years.
I have since dropped it from my certification but still use some of their workouts. Their philosophy is nothing new. It is just packaged in a different way than previous circuit training.
Greg Glassman did a great job of branding it and promoting the individuality of each box and that is what allowed it to thrive.
Let’s talk about if it is healthy or not.
It depends.
Each coach at each box will have drastically different experience, from a student who has never taken any other training and did the weekend Level 1 cert to a PhD in physiology. The challenge I saw was how it fit in with aviation. They generally don’t consider what we do when we do it and how it impacts our bodies. I could go down a long rabbit hole but suffice to say our bodies don’t identify sources of stress only that stress exists.
If you are doing long haul multi time zone transitions with lots of UV & cosmic radiation exposure who eats poorly and sleeps poorly adding in Crossfit will not do you any long term benefit. It may in the short but you will find yourself burnt out before you make many significant gains. That is where you’ll start to see thyroid dysfunction and chronic fatigue.
If you are younger than 30, you’ll probably see gains for a while. If you’re over 30, my experience is you’ll hit the wall fast.
For any aircrew I work with the program needs to be significantly adjusted to accommodate 1. Location 2. Time zones 3. Nutritional availability 3. Flight hours and training age of the individual. Without those (and many more) adjustments and knowledge the coach will be just randomly guessing where to take the client.

Our lives are more complex than any other industry when it comes to external stressors and adding another one can be of value, but it needs to be placed at the right place and right time with the right dose for the correct response. Without that, it won’t be healthy.


Oh and for nutrition. Just eat real food. The challenge is how do you do that when transiting airports and customs with regularity. I can be done it just takes planning. A specific diet may work for some but probably won’t work for most as each individual is unique in why the eat what they eat and how they respond to it all. I have added many carbs (sugar included) to people’s diets and they slim down. It just needs to be understood what is going on with them. And it is complex sometimes.

I wouldn't recommend crossfit to my worst enemy. I'm sorry for being blunt, but that's my opinion. It's backed by studies that find crossfit to be the most injury causing "sport" in existance. Pair that up with unprofessional and clueless trainers that usually operate the crossfit gyms, and you're in for a world of trouble.

^Ok, no peeing in the Crossfit coolaid! lol!

We've all heard those stories and statistics, and I tend to agree with you - to a point. Given the huge growth in Crossfit over the last 5 years, it was almost unavoidable that the quality of trainers would decrease; OTOH, there's lots of videos out there, caveat emptor, and check your ego at the door..

One of the biggest challenges I find is the various gym qualities throughout my layovers.

I’ve transitioned to more plyometric workouts and I think they are quite beneficial and don’t require equipment with minimal risk. Since the hotels have wifi, I find fitness blender (https://www.fitnessblender.com) a good spot to find workouts that you can filter to your time available. They are challenging and you just do what they do so no thinking required.

I read these articles debating the benefits of HIIT workouts but it’s my opinion they are great. I generally feel much better afterwards vice sitting in a hotel room and watching Dr Phil. I sleep better, am more focused and keeps me away from alcohol.

Unlike fightclub the first rule of crossfit is to tell everyone. I work as a full time firefighter with several high level very competitive athletes. The most injuries from exercise on and off our job come from the crossfit gym. If you are not planning on entering the olympics,why try to train like you are.


It is almost to the point that any of these type of wokouts on duty are pretty much banned by our members. We work out using interval training but not to the crazy extermes that this crossfit fad espouses.

Moderation in most aspects of anything is a good idea.

"Another study also found that young men who engaged in endurance exercise for more than five hours a week may up their risk of developing an irregular heart beat later in life by 19 per cent compared to men who only did less than one hour a week."
......you come to an anonymous forum and ask for anecdotes. I guess maybe those quotes may not be from the purported studies themselves but a cut and paste from some other forum? And then you attack someone because you don't like the way they respond. Most excellent.

upnatem I think its cute you want to participate with no facts or information whatsoever. As you know, avcanada is a forum for pilots, therefore, questions regarding the profession are welcome here. Please be objective, It's not about liking someones response or not, but if its actually contributing to the thread instead of just pissing on it and attacking the value of the question. Theres one reason forums have rules.
As you can see, there are several good replies from people that are as well interested in the subject and that give out pretty good recommendations on the subject. I want to invite you to read the whole thread again and don't engage in the negative responses. In regards to the cut and paste, I really don't understand what you are talking about.

Sounds like it's more a problem with the people being stupid than the exercise.

I know lots of chicks who do crossfit, some can hardly park a car without hitting something and they manage to not hurt them selves with crossfit. :lol:

I mean if you have no idea where your limits are, I really wonder how you have survived this long in life.

Well in your expert opinion you must be so able to assess exercise routines from 2000 km away.

I’ll let all the kinesiology students know that you are gonna put them out of work.

God i just love asshat posters who know everthing.

Sweet baby jesus.....

Do I know everything, no, do I know enough to be able to work out without hurting myself, yes.

If that's impressive to you, or sounds like a "know it all thing" to say, I'd wager you're easily impressed and know very little :roll:

I miss when people had common sense.
