Thank God for Drew Barrymore.

The actress, and our favourite flower child, has admitted to struggling with her weight after having children. It makes a refreshing change from celebrities who boast about getting their bikini-body back just weeks after having a baby.

The Santa Clarita Diet star is open about not having the kind of metabolism we assume celebrities are born with.

“Everyone is different, and I have the genetic makeup of the Pillsbury Doughboy,” Drew joked.

“I have to fight so hard to be in shape or be in a smaller size or lower weight, and people don’t talk about the fact that when you have kids, everything goes out but it doesn’t always come back in.

“You never get your ‘old’ body back, you’re working with a new body.”

The 44-year-old mum of Olive, six, and Frankie, five, feels healthiest when she’s working out but after one too many injuries she turned to Emsculpt. The innovative, noninvasive, body-sculpting treatment claims to work your core muscles while you lie back and relax.

It’s Drew’s “abs secret.”

“In order to actually be strong and healthy and exercise, you have to have a strong core, and that was just not in my grasp for the last seven or eight years,” she said at a press event for Emsculpt.

“I work a lot, my kids come first, and I was like 10th on the list, but I want to look good in my clothes, I want that illusive bitch: 80/20. I’m 44 and I’m asking ‘what are the next few chapters of my life and how are they going to function?’ I needed something to change my physical abilities so that I could actually start living my life.”

How does it work?

It’s the equivalent of doing 20,000 crunches in 30 minutes by emitting high-intensity electromagnetic pulses which force your core muscles to contract, thereby strengthening them.

Perfect for the time-poor among us.

A large swathe of fabric wraps around your core, with an attached paddle, as you lie back and let it do its thing.

According to clinical research, average results include a 19 per cent increase in muscle thickness in the six-nine months post-treatment.

The fat loss—a 19 per cent reduction—is a bonus. Not only does it look good, but less belly fat helps with heart health.

It’s recommended to start with four 30-minute sessions over a fortnight, with maintenance treatments every few months.

The initial treatment will set you back $4,000.

For Drew, it was worth it, helping her strengthen her post-childbirth abs.

“You know when you do a moment of core at the end of a yoga class and everyone groans, and it’s like, ‘you just sweat and worked out for an hour; what was it about that two-minute thing that made everyone moan simultaneously?'” she said.

“A lot of exercise pushes you really hard, but you’re not working your core enough.”

But Emsculpt alone won’t cut it. Drew also does two or three our-long workout classes a week and has overhauled her diet.

“I’ve had a 20 to 25 pound weight loss over the last few years, but it took so much dieting, so when the show would end I would inhale food, and within two months I would gain it all back,” she said.

“You can’t have that level of discipline without being miserable and going off the rails.”

Now, it’s all about 80/20. She reduces her daily intake of carbs, diary and meat so she can still indulge in pasta when its needed.

“I know that balance is the special sauce I want in my life,” she said.
