Zara Tindall was in ''so much shock'' when she returned to work following the birth of her first child.

The 37-year-old royal and Olympic equestrian has two daughters, Mia, four, and two-month-old tot Lena - both of whom she has with husband Mike Tindall - and has said that after making a return to horse riding following the birth of Mia in 2014, she found it difficult to get back into the swing of things.

She said: ''The first time around my body was in so much shock. It was like, 'What the hell have you done to me?'''

Zara is back in the saddle once again following the birth of Lena, and has said that her comeback this time feels much better than the first time.

She added: ''[My return] feels good, actually. I'd love to try and get back on the team. I'd love to go to another Olympics.''

The Olympian - who is the daughter of Princess Anne and Mark Phillips - won a silver medal when the games came to her home city of London in 2012, and she says she still gets ''goose bumps'' when speaking about it.

In a promotional video for her sponsor, Land Rover, she said: ''To be in London, the crowd, the whole Olympic experience, I can't tell you, it gives me goose bumps talking about it. It is incredible.''

Zara's return to horse riding comes after she previously suffered from two miscarriages in between the births of her two daughters.

The granddaughter of Britain's Queen Elizabeth revealed in November 2016 that they were expecting another child before she suffered a tragic miscarriage just weeks later, and told the Sunday Times earlier this year that there had been a second miscarriage that she kept a secret because it was ''too raw'' to talk about.

She said: ''You need to go through a period where you don't talk about it because it's too raw. But, as with everything, time's a great healer.''
