Nice study done by B Irwin shows that having a partner that exercises with you at the same time, even if online, is significantly better than going it alone. (Like twice as better!!)
This is a big win for why one would want to schedule simultaneous events. Also, if I have members that want/need to do more on an individual task, it is great to know I can bring in an online partner and get some well known group dynamics going.
Another aspect of this paper is that having a stronger online partner can help motivate the other.
