I don't do Chalean extreme, but this is a common reaction to a new, more challenging exercise routine. Your muscles will soak up water in response to the new demands you're placing on it. This water has to go somewhere, and can often result in some inches gained.
It should be temporary, though, and should go away as your body adapts.
