I’m getting a malware warning from this link.
Or jogging. It is by far the most time-efficient and accessible exercise.
More grist. (Gift link may have limits.)
Exercise strongly improves well-being—thanks, in part, to the positive effects on three neurochemicals that are associated with mood balance. These are the brain-derived neurotropic factor (which is lower in people with depression), serotonin (which modulates anxiety and mood), and beta-endorphin (a natural pain-managing peptide). Researchers have found that all forms of exercise are good for stimulating these neurochemical systems, but aerobic activity seems to have the strongest influence.
Not sure if I am completely convinced but a case made specifically for heavy to very heavy strength training in “older” (defined as a youthful over 60 years old) adults:
And defining heavy‐very heavy strength training as 80–84 and ≥ 85% of one repetition maximum, respectively. Basically last perfect form rep after four reps and several minutes rest between sets.
It convinces me of safety and efficacy just not of superiority compared to the more usual guidance of moderate weights in the 8 to 15 rep range. Or better yet mixing it up.
