What you're seeing locked are the "checkpoints" if you're on the Preview Screen after tapping a ride from the main menu (with the globe). Checkpoints indicate 5 minute sections within the tour. We lock these because we don't want users to unintentionally start in the middle of tours thinking it's a different location and miss the great scenery towards the start. Not only that, the workouts are designed to flow smoothly from one checkpoint to the next. Starting from the middle makes sense if you're continuing where you left off.
Additionally the locks also show how much progress you have made through BitGym's content. Over time, the unlocked checkpoints will be a scorecard of how much you have worked out. If you start from the beginning (the first available checkpoint which will be unlocked), you will seamlessly continue into the subsequent checkpoint. From the next time you select this tour you will find checkpoints you have reached to be unlocked, so that you can resume the tour from where you left off. The content is fully available to you.
Got it. My checkpoints still aren't unlocking.
Spotty internet connection or using multiple devices with the same account can result in this. We are working to improve the stability and consistency of checkpoint progress across the app. With BitGym 3.0, we store checkpoint progress locally on your device as well as on your online profile, so if one fails the other will keep your progress moving forward.
