Enough for an old man. Still not enough, can walk around the neighborhood. Tons of nature treks. Or just walk around the perimeter of your house… lot size in Austin is large, 0.25 acres to a few acres. Remember can jog on the spot while cooking, cleaning the house, etc. I walk a lot in a day, guess many of you are couch potatoes.
Remember exercise enough to stay healthy, not body building. The critical thing for a healthy lifestyle is blood circulation (depends on culture, have different terms), not building muscle, not burning fat, not staying in shape, etc.
In short, (intentional) exercise is not necessary for most people.
We conclude that measurement of muscle mass relative to body height should be added to the toolbox of clinicians caring for older adults. Future research should determine the type and duration of exercise interventions that improve muscle mass and potentially increase survival in well, older adults.
Study was done in 2015. So what exercise helps to increase longevity?
Taiji Yoga Correct? Essentially, increase blood circulation. No study on how good blood circulation increase longevity?
