Almost everyone here says the same thing. Exercise, even mild, even once, carefully, is highly risky. It's what the top ME doctors say too. Yet you still insist on pushing it forward as a good idea. It's not enough to say stuff like, each person should ease into it, set intensity according to severity etc. you aren't warning people about the risks. Worse you use an inappropriate example - about the road - which is completely different and just shows that you do not understand risk. Risk is about both the likelihood of something happening (which despite feedback you don't seem to take on board sufficiently) and about the cost attached if said event occurs. Again, your being told that it's severe, but your response shows that your not taking it inboard. At the end of the day you are ignoring what is tight before your eyes because it isn't in line with your tightly held beliefs, evidenced by your lack of movement. Ultimately your advice to a person with ME regarding exercise is to do it. It comes with some weak qualifiers that would be sufficient for someone well who is perhaps unfit, but which is wholey insufficient for the signifant majority of people with ME, including those with mild to moderate cases. We arent talking about getting ill if you start to heavy, or 'over extend' as you put it above, we are talking about getting ill from the sort of exercise that someone cautious might consider really mild and safe. You preach That it will improve their 'wellness'. Evidence does not support your view. Appropriate and responsible responses to the feedback you've had would be to a) change your view, b) modify your view significantly and disclose what you might consider only potential risks and consequences on your blog, even if you still hold to your belief in exercise as a good idea. c) do b while you look into this area in a lot more depth before setting your mind firm on the subject. But what you do is continue to hold firmly to this belief that 'exercise is good for most people with me'...that's where you still are isn't it? Someone will follow your advise and will get a lot more I'll. More people than will get improved wellness. And it will be your fault because your not offering this advice blindly, you have been warned of the serious repercussions, (even if they are being careful) but continue to offer it without sufficient warning. I don't think that's good.
