Agree, regular movement is key and even switching between sit and stand every 15-30m is not enough. We are working on an easy to adopt smart robotic chair along these lines to support more frequent useful movement without being as interrupting as a treadmill. Have a handful of prototypes out and looking for a few more early beta users in Bay area, NYC and Boston for July/August- if interested https://movably.typeform.com/to/y5NPOA2U
