We are unable to pause or freeze subscriptions I am afraid. All our subscriptions are processed, charged and managed through the App Store as in-app purchases. We don't own your subscription and for this reason we are unable to pause your subscription.
I would recommend in this instance that you cancel your subscription and rejoin once you are feeling better.
Once it is safe for you to return to your fitness journey, please Email me and I will generate a code that will cover your lost time.
Here are the directions you need to cancel your subscription:
If you are using an Android: https://support.google.com/googleplay/answer/7018481?co=GENIE.Platform%3DAndroid&hl=en
If you are using an iPhone: https://support.apple.com/en-gb/HT202039#whatnext
Please send us a screenshot of your cancellation for my records.
