Bydd y cyfyngiadau hefyd yn cael eu diwygio yng Nghymru i ganiatáu i uchafswm o ddau berson o ddwy aelwyd wahanol ymarfer corff gyda'i gilydd, ond dylent wneud pob ymdrech i gadw pellter cymdeithasol. Bydd rhaid i bobl ddechrau a gorffen unrhyw ymarfer corff o'u cartref oni bai bod angen i berson deithio am resymau iechyd. Mae hyn yn golygu, am y tro, os bydd dau berson yn cyfarfod, y bydd angen iddynt fyw yn agos at ei gilydd gan na chaniateir teithio i wneud ymarfer corff yn gyffredinol.
The restrictions will also be amended in Wales to allow a maximum of two people from two different households to exercise together, although they should make every effort to maintain social distancing. People must still start and finish exercise from their home unless a person needs to travel for health reasons. This means that, for now, if two people are meeting they will need to live nearby each other as travel for exercise is generally not allowed.
