"Dylai menywod beichiog nad ydyn nhw ar hyn o bryd yn gwneud ymarfer corff ddatblygu eu lefel gweithgarwch yn araf, ond dylai menywod sydd eisoes yn gwneud ymarfer corff rheolaidd barhau i wneud hynny, gan wrando ar eu corff ac addasu eu hymarferion yn ôl yr angen. Rheol gyffredin i bob menyw feichiog yw os yw'n gyfforddus, gallwch gario mlaen. Os yw'n anghyfforddus, rhowch y gorau iddi a gofynnwch am gyngor."
“Pregnant women who are not currently active, should build up their activity levels slowly, while women who already take part in regular exercise should stay active but listen to their body and adapt their exercise regime if necessary.  A general rule for all pregnant women is, if it feels pleasant, keep going; if it is uncomfortable, then stop and seek advice.”
