Can be summarized as "use it or lose it".

Counterpoint that becomes increasingly relevant as one ages: "wear and tear."

That's not a valid counterpoint. Assuming proper technique, frequent sustained use keeps joints healthier. In particular the old myth that running is bad for knees has been debunked.

I always like to show this picture as an example. https://i.imgur.com/ZcDedfo.jpg I don't have an original source but it shows a MRI leg scan comparison between a 40yo triathlete, a sedentary 70yo and a 70yo triathlete. The picture tells the story...

The patterns on the 40 and 70 year old triathlete match far too well. I'm calling bullshit. The "70 year old triathlete" scan is just further up the leg of the 40 year old.

It seems reasonable to me. I did a triathlon several months ago. One of the other competitors was 73. We finished with approximately the same final time.

Ctrl-F Testosterone - was disappoint. For approximately half of the population, supplementing testosterone into old age is a great way to maintain (and build) SMM along with that physical activity which TFA admonishes the lack of.

Coming from a family history of prostrate cancer, I would never consider testosterone replacement therapy.

At a certain age, the risk vs quality of life makes testosterone worth entertaining, atleast I think so.

Most people have no idea I'm 41, and instead think I'm in my 30s. Balding and grey hair show I'm not in my 20s ;) My 'secret' is I workout every single day . I might do heavy weight training, sled pushing, surfing, or a spin class. It doesn't matter as long as I do something physically challenging. I also follow an 80/20 rule on eating paleo-ish. Mainly I try to avoid processed foods, but I'll still eat a pizza or go…

What supplements do you take? Topical DMSO + magnesium ascorbyl magnesium phosphate is said to sometimes reverse balding. There are nutrients/vitamins/minerals associated with reversed greying. Vitamin D3, vitamin K2 MK-4, iodine/iodide, chelated/TRAACS magnesium, topical pregnenolone + DHEA (5 mg : 5 mg), nicotinamide riboside + pterostilbene, selegiline, MSM + silicon (monomethylsilanetriol) + vitamin C, astaxanthi…

I take Krill Oil and Creatine. For everything else I just try to eat a lot of varying foods.

I don't mind balding or greying so...

It's recommended that iodine/iodide (1,000 mcg+; add 200 mcg L-selenomethionine when taking higher amounts) and vitamin E (2 IU/g) are added when supplementing PUFAs. Iodide/Iodine binds with double bonds making the structure less prone to oxidation and vitamin E counters oxidation.

Most don't get enough vitamin D (and magnesium) even if eating well. 40-60 ng/mL 25(OH)D is a commonly preferred range.

It doesn't matter which cherry you pick, they all lead to the same conclusion: eating too many animals and not enough plants causes our most common diseases (obesity, heart disease, cancer, diabetes, stroke). Dr. Greger's agenda is not about the animals, it is about the people.

> eating too many animals and not enough plants causes our most common diseases (obesity, heart disease, cancer, diabetes, stroke) Do you actually believe that eating "too many animals and not enough plants" is the cause of diabetes (I assume you're referring to Type II)?

Yes, I do believe that, and yes Type II (not Type 1). According to Dr. Greger there is mounting evidence that fat is the cause, and that problems processing carbs is the symptom. Here are his videos with many studies cited: https://nutritionfacts.org/topics/diabetes/. Or Google type 2 diabetes and vegans. Here is the first thing I found: https://veganhealth.org/type-2-diabetes-in-vegans/. I'll take a 68% lower rate as some evidence. Vegans, by the way, are people who eat "too many plants and not enough animals". It helps with certain diseases.

> The motions are perfectly safe In theory, sure. In reality, not even close. I guarantee there isn't a single person in this thread who could tell me what someone's squat form should look like based on their femur:torso ratio and hip/ankle flexibility. Should they squat high bar or low bar? Wide or narrow stance? Parallel or below parallel? Flat shoes or heel lifts? If you can't easily answer all of those questions,…

> I guarantee there isn't a single person in this thread who could tell me what someone's squat form should look like based on their femur:torso ratio and hip/ankle flexibility. Flat lumbar, stance roughly shoulder width, though exact placement is up to the individual's preference and morphology as long as it doesn't induce valgus collapse. Knees tracking over toes to avoid shear forces on the hinge joint, hip crease…

My favourite Rip quote is "A weak man is not as happy as that same man would be if he were strong. This reality is offensive to some people who would like the intellectual or spiritual to take precedence. It is instructive to see what happens to these very people as their squat strength goes up."

Wow, thanks so much for sharing.

this must be one of the most important medical documents out there. I can't believe that after reading thousands of words in magazines on aging I never saw this! One could ask how much more exhausting it is for someone to do a triathlon at 70ya. But I remember someone in my family really enjoying being very active right until they dropped dead.

That is such a positive message.

Speaking as a former bike racer, cycling does not build muscles unless you are already wildly out of shape. Pedaling in a tall gear still isn't much resistance, typically less than body weight. Muscle is built only by getting near the limit of musclular strength. Cycling only challenges your cardiovascular system. I always squatted and deadlifted to get better at sprints. Other racers who were climbing specialists ha…

Is climbing a good sport according to this 'limit of muscular strength' requirement?

I wear my arms out pretty fast rock climbing, but that's only a small proportion of the body. I kind of doubt it is a good replacement for strength training.

You do that on empty stomach? Serious question, it's my main difficulty with morning workout.

I've found that what I can do - immediately - in the morning depends on exercise intensity: Running/swimming/cycling: anything at or around low aerobic threshold (Friel HR zones 1, 2, or 3) Strength: Endurance-focused compound primary exercises (e.g. squats, deadlifts); any form of auxiliary exercises (planks, bicep curls, etc.) Anything more than that and I need to wait at least 2-3 hours after waking up (e.g. cardi…

I would feel some gut "pinch" when I would run after eating something -- more like a mild cramp on my left side. Once I stopped eating before a run, the "cramp"s have gone away, and I can go ~5mi going at a moderate (11min/mi) pace.
