I am trying to set up VO2max on my iPhone. I cannot find the "SET UP" button.

Thank you for your reply. I have read and followed the steps in the article you reference many times.

But when I get to Step 3, I have NO SET UP BUTTON to tap.

I cannot get past Step 3.

That is my problem.

Thanks

My problem is I don't have a SET UP button on the VO2 max part of the Health app.

Is it possible that the reason I don't have a SET UP button is because my iPhone already has this set up. But when I look for data, it says NO DATA.

if I click on ADD DATA, it takes me to a page with the DATE, the TIME and a blank box labeled VO2 max and a flashing cursor that shows it wants me to enter something in this box. It also brings up the number keyboard for me to use to enter something in this VO2max box

Are you saying that I must wear my Apple Watch for 24 continuous hours?

I take it off at night and charge it.

So if I don't wear it for a straight 24 hours then it can't determine my VO2max?

Do you think this is the problem?

BTW, I am over the 20 years old criteria.

My country is USA.

I have Apple Watch series 5.

I have the latest software OS on my watch AND on my iPhone.

Thanks

Perhaps, I don't work out long enough and vigorously enough for the iPhone to collect VO2max data for me.

Thanks for all your effort to help me.

I really appreciate that.
