Kimberly Wyatt thinks women are under too much pressure to lose weight after giving birth.

The former Pussycat Dolls singer - who welcomed her daughter Willow in December - has spoken out to reveal she worries new mothers are put under pressure to lose weight too quickly.

Drawing on her own experience she said: ''You have to exercise when you are ready and your body will tell when you are ready.

''I had to have an unplanned caesarean, which meant that my tummy muscles were severed during the birth. Getting back into shape after Willow was born is something that didn't happen quickly, I couldn't exercise for six weeks afterwards ... Once I had the all clear from my doctor, I started to do gentle exercise.''

The 33-year-old star has now designed a dance-inspired fitness routine to help mothers of all age to get back into shape as she found she was unable to do the same kind of workouts she did pre-pregnancy after welcoming her and her husband Max Rogers' first child

She told Closer magazine: ''I suppose I was nervous in a way that I didn't actually realise how much my body had been through until I tried to do all the things I did pre-pregnancy. By the time I got back to the gym, I'd lost a huge amount of flexibility, but I was excited to start working hard to get my pre-baby body back!''
