3 times a week only one hour per session

usually 3 times a week. but you can include physical activity there too like regular walking at work or lifting or anything that makes your body move more than when its at rest so more than 3 times a week for me

Maybe 9 hours a week.

Once every 1000 years i.e. almost never.

Almost every morning for half an hour..,

once a week
