Series 2 and water aerobics

see the following:

About Apple Watch water resistance - Apple Support

Since you can swim with it, I don't think water aerobics will be pose any issue.

Apple only says there is a swimming workout app, you'll have to find the best fitting workout type, when you receive the watch: https://www.apple.com/apple-watch-series-2/

Workout AppSweat the details.

Choose from 12 indoor and outdoor workouts — including swimming, biking, running, and elliptical — then set your goals and get moving. However you work out, Apple Watch Series 2 accurately measures your movement. Select up to five metrics to view at once, automatically pause a run, and even mark segments.

Since the watch series 2 is water resistant up to 50m, you will be able to see the workout details in water and even listen to music.

Apple Watch Series 2 is rated water resistant 50 meters,1so you can leave it on when you’re in the pool or ocean. Since a speaker can’t be sealed because it needs air to produce sound, we reinvented ours — it lets water in, then uses sound vibrations to force it back out.

Hi

The Workout app will include two swimming activity types: Pool Swim and Open Water Swim.

Both of these new activity types are designed to calculate calories and track laps (pool) based on your swimming stroke, so would not be appropriate for water aerobics.

As water aerobics is not just continuous swimming, your best option may be to record your activity as "Other".

Probably the closest match to the activity type may be Elliptical.

But it may not be 100% accurate however.

I came here looking for similar information. I do deep water jogging and have been anxiously waiting for a waterproof version of the Apple Watch. I currently use a Garmin watch with heartrate monitor and am hoping the Apple Series 2 will have a setting that gives accurate feedback for non-lap swimming exercise in the pool.

You can definitely keep your watch on in the pool during water aerobics. As far as I know, it won't track your activity as specifically water aerobic activity, but it must likely will monitor and count as general activity. I can bet that there will be (if not already) a water aerobic activity app soon. In fact, with Series 1, there was a swimming app, although the watch technically was not considered water proof... and I never dared try it. I think you'll be happy with your purchase and fun of tracking your activity on your watch! Cool!

I'm also very curious about this, because as well as water exercises i also do stationary swimming (swimming in my spot as you would with a swim spa or using a bungee cord) and looking swimming workout options for pool swimming you have to set the length of the pool and for open water the watch uses GPS.

So i think we would have to wait for third party apps to be released for these activities. It would be interesting to see how they will measure the workout because the water can affect the heart rate monitor.

But either way I didnt buy the 1 gen apple watch because i was waiting for the waterproof one and now that its here i am very excited.

I'm also wondering the same thing. We could set the activity to "other" or "elliptical" and manually lock the watch for water but since Apple says that water may interfere with the heart rate monitor, I'm not sure how accurate the tracking will be. Apple says that other indicators like GPS and accelerometer are used instead but in water aerobics GPS isn't useful so does that mean all tracking would be done with accelerometer? I plan to give it a try with different settings including pool swim and see what happens but I'd love to hear other solutions and how accurate they might be.
