So what about those times when you travel and you don't have your belt and three blankets, how will you do your inversions?
I travel by train.
Here is a picture of my yoga room for the next 24 hours
While there are times when there is a layover, I feel odd doing down dog on a train platform. Although, I sometimes sneak around a corner to do a handstand or standing pose. Luckily, in my sleeper the seats go flat, and I can have a seated and supine practice. It was only on this trip, as I mulled over an execellent Paul Cabanis restorative, did I figure out a way to get a longer inversion.
I also experimented with a standing pose. There's a lot of movement on a train, but I was able to wedge myself into Virabhadrasana 3
