Hello @Donna47
Are you starting the exercise from a shortcut on your Charge 5 or letting automatic recognition work? It may not recognize Water Aerobics automatically if you're not really running about.
It might be an idea to set up an Exercise Shortcut so you can control the Start and End time, and tell your App you're exercising so it registers.
There are a couple of options here:
One is to set to Swim and then change later. If you choose Swim, the water lock automatically comes on to protect your Charge 5 from the water, which is great. A downside is that it can be difficult to disable water lock (you need to practice a bit before you need it) and that can be frustrating for some people as they find it hard to switch it off and stop their exercise session.
The other option is to choose another Exercise Shortcut, eg Workout and then change it later.
If you want to set up an Exercise Shortcut, go to the Today screen in the App on your phone. Tap your profile picture, then Charge 5. Tap on Exercise Shortcuts. There should be 6 already there. Choose one you'll never use, swipe left and choose Delete. Then a + Exercise Shortcut option should appear at the bottom. Tap that and choose Workout (or something else).
Sync your Charge 5 and it should show up under Exercise (you scroll up to find the other exercises).
Press Start when you're ready and Stop to finish.
When you've finished your exercise session, you can rename it in the App. Tap on the exercise session, at the top right tap the arrow to Categorize Exercise. Start typing Water in the search box, and Water Aerobics will appear as an option. Tap that and it will rename the exercise for you.
I hope that helps to solve your problem.
