Denise Richards Abs Secrets Unveiled at 55

She found fame in the Nineties as the ultimate pin-up girl. 

And three decades on from her lads' mag heyday, is still looking just as incredible after implementing her diet and exercise regime. 

While she celebrated her 55th birthday on Tuesday, and is a mother of three children, the former Playboy model still has abs to envy. 

Although she has been the subject of plastic surgery rumours, she has insisted this isn't the case, stating: 'I have only done my boobs and I am very open and honest about that. 

'I have had the same nose, if people look it up, and the lips.' 

So how does Denise maintain her incredible figure? 

In 2019, Denise went gluten-free after Real Housewives viewers pointed out her enlarged thyroid during a reunion episode.

Speaking about the change in her diet, Denise told her followers: 'It’s amazing to me in a short time eliminating gluten from my diet how much my thyroid has changed. 

'A few of you pointed out after the #RHOBH reunion that my thyroid was enlarged. You were right, it was something I ignored until pointed out. 

'I had no idea how much our diet really can affect our body and for me how toxic gluten really is ... I thank all of you who sent me messages. #selfcare'. 

The Two And A Half Men star also reintroduced meat and fish into her diet in recent years but said she doesn't stick to the three-square-meals-a-day rule, instead preferring to snack on small means. 

She told Women's Health about her diet: 'Usually I like lunch or dinner food for breakfast, but sometimes I'll do typical breakfast food, like an omelette with buffalo mozzarella, tomato, and basil.'

On her lunch routine, she added: 'I would say that I'm a bit of a grazer. I like doing a plate of fresh cut-up vegetables, like cucumber, tomato, carrots, and celery with crunchy sea salt. I also love fresh cheese, so I'll do that and nuts throughout the day, too.' 

While she tries to get into the kitchen and make dinner for the family, telling the publication: 'I love to cook. I'll roast a chicken and yellow potatoes with carrots. 

'I also love artichokes. I'll steam them, bake them, and drizzle balsamic on top.'

When it comes to exercise, Denise focus on exercises like Pilates and dance, while she's also keen on hiking.  

'My secret to staying in shape is consistency,' she told Huffpost. 'When I consistently stick to my routine, that is when I feel my best.

'I also think you need to work out for your own body. Just because something works for someone else, doesn’t mean it will work for you.' 

Asked about the secret to her incredible abs, Denise told Self: 'I am very active. I found what works for my body- everyone's body is different. 

'For me it's Pilates and dance. My abs get the best workout with my Pilates reformer - I had two C-sections and it was the only thing I found that got my tummy flat.'

Denise has also endorsed non-surgical body contouring treatment. 

She revealed she's a fan of Emsculpt Neo - a mini machine that combines HIFEM (high-intensity focused electromagnetic technology) and RF (radio frequency) energies for fat elimination and muscle building.

Strapped to the stomach, the device fires electromagnetic pulses deep into the abdomen, which forces every single muscle to suddenly tighten, inducing 20,000 muscle contractions in 30 minutes - the equivalent of no fewer than 20,000 sit-ups.
