It's not really moving the goalposts since in overweight and obese people the disk can damage by improperly lifting their own body weight - and that matches well with the demographics for low intensity physical exercise like 10000 steps. So I'm not against burpees and if it works for you that's good, I would avoid recommending any spinal stressing exercise to a broad demografic where it can do more damage than good for some. Seen in this light, his answer makes sense: the exercise that you should NEVER do is probably safe for most people, but could be detrimental for enough otherwise healthy people for him not to endorse it. A classic case of a few of us ruining it for the rest of you. Thank you for the kind words.
