Fit to be pregnant
Currently there seems to be a consensus that maintaining light to moderate physical
activity during an uncomplicated pregnancy has several benefits for the health of the
woman and the fetus [1–5]. In the last two decades, scientific evidence has clearly
supported the importance of physical activity and exercise during pregnancy [6–11].
In the first place, one should clarify the meaning of these terms, because sometimes
the terms physical activity and exercise are used interchangeably, and there is no
clear consensus on the definitions of fitness or exercise prescription.
