Pippa Middleton reveals the one thing she won't give up during her pregnancy

Pippa Middleton, who confirmed she was expecting her first child last month, has revealed the one thing she won't be giving up during pregnancy.

The expectant mum confirmed the rumours that she was expecting her first child with husband by saying that while she was understandably worried about continuing her fitness regime, she believes that keeping active will help her during pregnancy, birth and recovery.

Now the 34-year-old has revealed that, as an avid tennis fan as a player and spectator, she will keep practising the sport.

She wrote in her column for Waitrose Weekend magazine: 'I've been a tennis fan since childhood, as player and spectator, and have been keen to continue playing safely throughout pregnancy.’

Kate Middletton, who's experienced pregnancy three times already, will very likely be on hand to give her sister advice

Mentioning tennis pro Serena Williams, who famously won, she added that while the mum is healthy, well-trained and there's no complications with the pregnancy, she doesn't see a problem with carrying on playing tennis.

'Take Serena Williams – she famously proved that women can play a high level of tennis from two months (when she won the 2017 Australian Open) up to eight months.

'Few of us can relate to this elite excellence, but if you're a healthy, well-trained player with an uncomplicated pregnancy there's no reason why you can't continue a good level of tennis.'

At the time when she announced her happy news, Kate's sister revealed in her column that she wasn't sure if she could still continue to workout or not.

She wrote: 'I was lucky to pass the 12-week scan without suffering from morning sickness. This being my first pregnancy, I had so many questions I felt were still unanswered.

'I wanted to know things like — would I strain if I served in tennis? Are all strokes of swimming safe? Can I still do a normal yoga class if I avoided certain positions? Could I still work my abs?'

This will be Pippa's first child, and the lovely baby news came about a year after she tied the knot with James Matthews.
