Research into High Intensity Interval Training (H.I.I.T.) shows the benefits to fitness with only 60 minutes of exercise per week. There’s an instructive video at this link. How little exercise can we do and still get maximal health and fitness benefits?
”The answer appears to be a lot less than most of us think — provided we’re willing to put in some effort. That’s the secret behind high-intensity interval training, or HIIT, an approach to training that compresses all of your exercise into only a few minutes.”
(I know I’d have more time to exercise if I stopped watching videos on how to get fit.)
