Dame Jane Seymour has always had a 'try anything' attitude about maintaining her sensational 5ft 3in figure, but there's one type of exercise she won't add to her fitness regimen.

'I've had to actually tell myself that when I go into a group class, especially something like yoga, that I have to tell myself I am not going to win, because I'm way too A-type,' the 75-year-old Emmy winner told Fox News Digital on Sunday.

'I want to win! Which means that I can never have done yoga, and I will decide that I could turn myself into the pretzel like that person. No. No, I cannot.'

Seymour (born Joyce Frankenberg) continued: 'I'll end up in the hospital or something, so my approach is to try everything, but do it the way that I know I can. So, I listen to my body.'

Instead, the Harry Wild producer-star does ballet barre, sit-ups, light weights, walking up and down hills, Pilates and Gyrotonics.

As for Seymour's diet, she sticks to Mediterranean fare, stays away from most starch and drinks very moderately (except while filming) but she never wants 'to think I'm on a diet.'

The Dr. Quinn, Medicine Woman alum grows her own organic food and has chickens at her Malibu home, but she only consumes one big meal a day around 1:30pm.

As for plastic surgery, the British grandmother-of-four admitted on Steph's Packed Lunch in 2022 that she had her 'breasts improved' at age 40 as well as a 'minor' eyelift in the nineties.

Seymour is set to walk down the aisle for a fifth time as she just announced her engagement to doctor-musician John Zambetti after nearly three years of dating.

'It was actually Valentine's Day, the day before her birthday. I thought, "This is insane. I'm just gonna do it,"' Zambetti told People on June 12.

'I got down on my knees, the whole thing. I had the ring hidden in the safe, pulled out the ring. I opened the box, and the ring popped out of the box, onto the bed.

'Then I had to climb under the bed, and then I couldn't get out, and she had to get out of the bed and pull me out of the bed.'

The former Bond Girl added: 'And we weren't wearing any clothes.'

'For us, the most important thing, it's about us and about our families,' Seymour said of the ceremony.

'We've got a lot of very close friends and no one's getting any younger. So I think at some point there will be some [sort of celebration or ceremony.]'

The two-time Golden Globe winner welcomed four children - daughter Katherine, 44, son Sean, nearly 40, and twin sons John & Kristopher, 30 - during her marriages to James Keach and David Flynn.

Seymour executive produces and stars as the titular Harriet Wild, a retired literature professor, in the six-episode fifth season of David Logan's detective dramedy, which airs Mondays on Acorn TV.

The Twelve Dates 'Til Christmas star - who became a naturalized US citizen in 2005 - runs her own scarf company Jane Seymour Designs, her charity Open Hearts Foundation and she's penning a memoir.
