Walking just 4,000 daily steps once a week cuts risk of early death in older people, study suggests
How can you do something daily once a week?
They mean 4000 on a single day once per week, i.e. not just 4000 steps per week spread over multiple days.
You could read it as "meeting the daily quota just once a week has noticeable effects already".
But it is a weird way to word that headline
Does 'daily' always mean every day or can it also mean per day?
It can mean both, apparently.
