Zara Phillips has said that it took time to "regain" her fitness after giving birth to her daughter.
The 33-year-old equestrian asserted that she rode "very briefly" from around five weeks after her daughter was born, adding that there was a period where it was a little bit like working against yourself, the Daily Express reported.
Phillips added that it was "quite frustrating" losing muscle while pregnant but one has to finally accept it.
