HIIT is great.
It’s even better when you follow it up with moderate movements throughout the day to keep things lubricated.
One thing researchers found in common with all the longest lived peoples in the world was the tendency to keep moving throughout the day without much stoppage.
Yes...Today I rearranged our family room furniture by myself, mopped our wood floors...and have walked 3.07 miles (inside the house)...going out for a walk soon. Does that count? PS...I have a 12 Min HIIT program I do 1-2 times a week, and Pilates. But I am thinking of adding a once a week bicycle HIIT program. Can’t run (hip problems).
