Which workout should I select when im in TRX class?

Please note that the following is not medical advice and you should consult a physician to give you their professional opinion before you apply the following :

That's a difficult question to answer as it will depend on how intense your TRX session is:

1. You go from one exercise to the next within 30 sec and keep a high hear rate: Select HIIT
2. You rest between exercises for more than 1 min and you heart rate drops: Select Functional Training or Traditional Strength Training.
3. If none of the above, select the "Other" workout: it will not track as well your workout but you'll get credit for it

Lastly there are some apps on the App Store that purport to track TRX workouts. I have not experience with them but you might give them a try.

This is a user-to-user technical support site operated by Apple, you aren't exchanging information with Apple technicians. Expecting volunteers to know what TRX is, or look it up if they don't to answer you is a bit much.

You are welcome!
