A couple who have been married for 17 years have gone viral after sharing their top tips for a successful marriage — and the number one piece of advice revolves around the bedroom.

Lisa Bilyeu, the co-creator of health brand Quest Nutrition, and her husband Tom took to Instagram to share the secrets to their almost two-decade long relationship, news.com.au reports.

Explaining one Instagram post "just ain't gonna cover it" she did her best anyway, sharing a photo of the pair holding a whiteboard adorned with nine pieces of advice they'd learnt over the years.

And the couple's top tip for ensuring a relationship goes the distance read: "Have sex often."

Other golden nuggets of love life advice included "forgive mistakes fast" and "hold each other to a high-ass standard".

The photo, which has been shared on both the couple's Instagram accounts, has quickly gathered a lot of attention, many people thanking them for being so "real" and "honest".

"So amazing!!! Thank you for sharing this!" one follower said.

"So true!!! Very wise words," another agreed.

"I love this and how you're looking at him," someone else wrote.

Lisa explained the pair had compiled the list together for the podcast she hosts, Women of Impact, which she started after she and Tom sold Quest in August 2019 for $US1 billion.

Since then, the health guru has created similar lists that have gone viral in the past, such as "how to be more confident" and "five things you should never settle on".

#TBT to 2012 when the hubby and I saw Quest bars on a store shelf for the very first time! And this photo ABSOLUTELY reflects how excited and happy I was. ELATED is the word I think best describes it! We had put our entire lives on the line to build the company. Our house was at stake. We chose to hold off on starting a family. Everyone thought we would fail. So this moment… this major step towards our dream was…. well… validated. And while I do actually struggle with whether I should WANT validation or not, I have realized that I actually get better results by striving for them. So, I have embraced it instead of fighting it! . BUT… yes of course there is a but 😉... a key part of this for me was making sure I don’t RELY on the validation! Because the chances are… 99% of the time things DO NOT go according to plan! So making sure that it doesn’t dent your enthusiasm is the other VERY important piece to this strategy! . So what small validations have you guys had recently that you own with pride?

One titled "the worst advice I ever got" listed marrying her husband and risking their home on a protein bar – the product that launched the company they went on to sell for a life-changing amount.

"Only YOU live with yourself in the dark at night," she captioned the post. "So only YOU should be the one making the decisions ABOUT your life! And look … sometimes it works out and sometimes it doesn't. But man when it does."

"This is the best thing I've seen recently, speaks volumes to personal choice for ones journey and purpose in this experience!" one person commented.

"That's so powerful," another said.
