Is a daily 7-minute workout enough? I perform it at a very high intensity (40 jumping jacks, 16 push ups). https://archive.nytimes.com/well.blogs.nytimes.com/2013/05/0...

For 80-85% of maximum pulse rate... If your lungs are burning and you're about to collapse after 30 seconds of activity the intensity is about right. Do 30 seconds high intensity, then 90 seconds low intensity (don't sit down or stand still), repeat 8 times. Rowing and sprinting works really well.

Would swimming work as well? I can see myself doing some laps really fast that will leave me panting by the poolside after 50 mts.

I believe running your heart at such high intensity every day isn't particularly healthy. It causes scarring of the heart tissue and possible problems as you age.

I think watching this Ted might be helpful: https://www.youtube.com/watch?v=Y6U728AZnV0

How does one determine maximum pulse rate? I do workouts where I'm constantly at 160-170 bpm for 15 minutes and my lungs aren't burning nor am I about to collapse (aged mid-30s, if that matters)

CDC says 220 beats per minute, minus your age in years:

Or buy one 30lb kettle bell. No running shoes, low cost, no finding space in your home, no buyer's remorse.

A swing with good form works your entire body. 100 reps once or twice a day literally takes 2-4 minutes. Do it after hitting start on the microwave.

I've heard that estimate before (80% would be ~150bpm for me). But then the physiological effects described by the GP don't seem right as I need to go much higher to feel anything like "my lungs burning" (maybe 190+?)

IN MICE link to full paper: https://aacrjournals.org/cancerres/article/82/22/4164/710131...

From the abstract:

  Epidemiologic data from a 20-year prospective study of a large human cohort of 
  initially cancer-free participants revealed that exercise prior to cancer 
  initiation had a modest impact on cancer incidence in low metastatic stages 
  but significantly reduced the likelihood of highly metastatic cancer.
Data was gathered from a large cohort via questionnaire. Looks like the study then used responses to classify high vs low intensity.

From the article:

  The total study population included 2,734 participants; 243 new cancer cases 
  were recorded during the 20-year follow-up period. 
It reads as if the study then had to reject data from 95 of the 243 patients due to not having a SEER score.

From skimming the article, I can't find any analysis of metastatic disease incidence in the remaining patients? Am I just missing it?

It might sound stupid but work as hard as you can and note your maximum.

I’m 180bpm-ish as a 45 year old male, I get that trying to cycle uphill as hard as I can and can sustain it for some minutes.

They say the equation is 220bpm minus your age, so you should be able to go a bit higher.

5-10 minutes of high intensity exercise daily is well outside what that Ted talk was describing.

With up to 45 minutes of daily exercise you see an improvement. After that there is a period where more exercise has negligible impact and only at the extreme upper end to you see a decline. But even people running regular marathons have lower risks than couch potatoes, you need to get really extreme before it’s an issue.

I am layman but can somebody explain this? Even if blood sugar level dips during the exercise it comes right back immediately after. Even if you exercise a lot, for majority of the day your blood sugar level should be nominal because nobody can exercise at the effort needed to dip your sugar for very long. So does this mean cancer cells are so hungry for sugar that they can't survive even a short term dip in sugar av…

Surely there have been studies on simple carbohydrate intake correlated with cancer incidence? I suppose it's hard to do a multi-decade study on something like this but it may be possible to gain evidence.
