What is the time period for this statement? I'm assuming that must be weekly, but everywhere else in the report, the units are daily.

"Adults aged 18–64 years should do at least 150–300 minutes of moderate-intensity aerobic physical activity;"

EDIT: Added quotes for clarity.

Yes it's very confusingly worded.

"->Should do ... ->Or ... Throughout the week."

Not sure why they worded it that way, maybe adults with busy schedules engage less with _ per day than _ per week recommendations.
