The big benefits in my opinion are It's a gateway "drug" into fitness. You just played a game, then you increased the intensity and did it a bit longer and suddenly you did a 30 minute cardio workout sweating like mad and most importantly the endorphins your body releases during exercise are real as well. So you are very likely to do it again, and again. And that's the important part, sticking with it. The second thing is that in the headset time feels different so you are more likely to workout for longer than you would have while doing crunches staring at your living room wall. And there are already several multiplayer experiences that can be counted as a workout (Blaston, FitXR, VZFit, Holodia and also our game VRWorkout) which adds a whole different level of exercising together.
