Our expert says:
Two reasons. One is that as a result of training, you increase muscle mass. That means that even if you lose fat mass, your overall weight stays similar. People often gain weight as a result of this. Then the other reason, more for someone who has just begun training, is that their blood volume goes up - you can produce a whole extra liter of blood and that means 1kg increase in mass.
SO what you're feeling is a positive response to training, it probably means lean mass is going up. There is another possibility and that is that your training is causing your overall energy use to exceed your intake, and you're losing fat mass. But I think that given that your mass has stayed the same, it's more likely the former.
