Victoria Beckham says wanting to be really thin is 'old-fashioned'

Victoria Beckham says she thinks wanting to be thin is an "old-fashioned attitude" and women today instead want to look "healthy and curvy".

The Spice Girls member and fashion designer, 48, is the new cover star (14 times over globally) for GRAZIA, as she introduces her new collection VB Body - which apparently looks best on curves.

After spending some time with her family in Miami, Victoria was inspired by the body confidence of the women in the Florida city, which partly inspired the shape of her dresses.

"There are a lot of really curvy women in Miami, and they really own it, you know?", she told the magazine.

"They walk along Miami beach with not a lot of clothes on, and they look fantastic. They show their bodies off with such confidence. I found both their attitude and their style really liberating.

"And as a mother, I loved that Harper was around women who were really celebrating their curves and enjoying how they look."

The star shares Harper, 10, as well as Brooklyn, 23, Romeo, 19, and Cruz, 17, with husband David.

"It's an old-fashioned attitude, wanting to be really thin," Victoria added. "I think women today want to look healthy, and curvy. They want to have some boobs – and a bum.

"The curvier you are, the better my VB Body dresses look."

Sizes of the collection – which include flattering figure-hugging jersey dresses she calls "sucky-sucky dresses", reminiscent of her earlier style – range from a UK 6 to 18, with colours to compliment a range of skin tones, prices starting at £90.

Victoria said she wants the line to be inclusive of body shape, skin colour and budget, adding, "This isn't just about me."

While she's known for her petite frame and disciplined eating habits – only eating grilled fish and steamed vegetables according to David – she makes it clear this is irrelevant.

"It's not about being a certain size," she told the magazine "It's about knowing who you are and being happy with who you are.

"I have found my own balance between wanting to have fun and being disciplined about eating healthily and working out. When you're younger you fight against that balance, but through being older I've reached a place where I know what that balance looks like. I just know what works for me."

And part of what works for her, it seems, is getting "as a good a bottom" as she can get. "Every woman wants a nice, round, curvy bottom right?" she said, with the intention of her well-fitted dresses to accentuate this.

Victoria has gone from focusing on cardio, to lifting heavy weights, which has helped with her muscle tone – and other than her personal trainer, her workout partner is often David.

Speaking on this switch up, PT Bobby Rich told Women's Health UK earlier this year, "It was becoming apparent to her that the benefits from her own training routines has become minimal.

"Despite spending 90+ minute sessions in the gym she was purely maintaining her fitness levels rather than improving in other meaningful ways. She was ready for a change."

In terms of what this change involved, he added. "Proper strength training maps out a plan of increased reps, weights, and modes of movement.

"While Victoria was used to smashing her workouts week in and week out, she didn't necessarily have measurable goals the way that she does now." They began measuring her output within each session, by either increasing her range of movement or the weights she lifts.

Rich said the biggest change in her training week was introducing structure and progression. "We did this by incorporating training cycles, or blocks of time that focus on different aspects of fitness (strength, endurance etc) which would allow her to improve, peak, maintain, rest and repeat."

More about quality than quantity, he added, "An important point I wanted her to understand – and that most people struggle with – is that a 35-minute session can at times be more beneficial than a 90-minute session. But we got over that hurdle pretty quickly!"
