Tick the remember me box and suffer no longer as your details will be saved. - A few athletes pointed this one out too: Music & podcasts will now play again while you are training hard, sorry you had to sweat in silence these past few weeks. - Somehow our gym open times had -1 instead of 0 for empty time slots. Not even sure how you do that, but it's fixed now so we will stop the philosophical pondering on negative attendance. - Adjusted interface for Core Advantage members booking class times - buttons now look more button-y and the words are good-er. - Bug work in progress: There may still be some delay between setting up an ongoing bulk enrollment and it becoming visible in your schedule, we did a little work to speed this up, but stay patient with it, as they might not all appear straight away. ***Version 2.0.0*** Core Advantage members can now book and change their training schedule. Simply log in using your account email address and date of birth (DDMMYY format) to view and book times in the gym. *Parents and guardians can also log in using their email address with the date of birth of any of their children/dependents ***New in version 1.2.0*** - Fartlek Timer.
