Australian fitness blogger Kayla Itsines has taken to social media to share a photo of her post-baby body taken only a few weeks after giving birth to her daughter.

The side-by-side photo shows how she looked just before the birth of her little girl Arna Leia Pearce, who arrived in late April, compared to now.

The new mum proudly shared the snap, despite admitting great fear.

"If I am honest, it is with great trepidation that I share with you this very personal image," Kayla said in the caption.

"Every woman's journey through life but especially pregnancy, birth and healing post-birth is unique."

She said regardless of how her body healed post-birth, she felt it was really important to embrace, appreciate and celebrate her body.

"The same way that I tell all the women in this community to celebrate their body."

Kayla, who announced on April 30 the arrival of her first child, said she will continue to celebrate her body for all it has been through and the absolute joy it has brought into her life with Arna.

"As a personal trainer, all I can hope for you ladies is that you feel encouraged to do the same regardless of whether you have just given birth or not, celebrate your body and the gift that it is," she told her 36 million combined Instagram and Facebook followers.

"No matter what journey you have been on with your body, the ways in which it heals, supports, strengthens and adapts to take us through life is truly incredible."

In a previous post, Kayla had revealed her daughter with fiance Tobi Pearce arrived via caesarean after advice from doctors.

Muffin update 💛💪 30 weeks vs 36 weeks #pregnant 💛💪 From the start of pregnancy to now, I have gained almost 12kgs 😁(26 pounds). I’m definitely starting to slow down (not by choice😂). I am still eating well, staying active and sleeping .. ‘okay’ (just a little uncomfortable). For the ladies who don’t know, or who are new to my page, @tobi_pearce and I are having a baby girl! She is measuring one week and 2 days ahead in size. This puts her in the 91st percentile for weight😂 So proud of my little muffin haha!! I think we have FINALLY thought of a name, which we will announce at birth! I have a whole Instagram highlight section answering any FAQ’s! If anyone has any more questions for me (after reading the FAQ’s) comment below! 🥰 www.kaylaitsines.com/app

Good morning ladies!!/Good night from Australia!!! I STILL have some ladies asking me about AB workouts during #pregnancy. I have NOT been trying to target or isolate my abs (and do NOT recommend it due to safety)! My #activepregnancy routine is very different to my "normal" routine! During this pregnancy my focus has been on walking, postural work and light workouts (when I can fit them in). I'm happy because weight gain is on track and WELL within what is "safe" and expected for pregnancy. I will re assess my workout routine #postpregnancy and when cleared by my doctor will start making re-introducing abdominal training. Until then ladies, NO ab workouts for me 😁😁www.kaylaitsines.com/app

"I was a little bit sore, but after a couple of days I was generally fine, just no lifting other than Arna. Now, I just need to rest, eat good food, drink lots of water and I'll be okay," Kayla said.

The creator of the Bikini Body Guide and co-founder of fitness app Sweat said she couldn't describe how she felt when she heard her little girl cry for the first time.

"In that second, we heard her cry for the first time, the doctors and nurses examined her quickly, bought her over to us and said 'she is absolutely perfect'. My doctor said 'Look at that hair and those cheeks! Amazing!'"
