Cundy revealed on this Instagram post that she plans to get in shape in 2022, and one of the ways she will do so is using the elliptical more. Even if she is wearing high-heeled boots and a fancy dress, like she is in the video, she will be using the elliptical. She captioned the post, "My New Years resolution is to get fit for 2022…so I decided to keep it glam ,do it in heels !!"

Cundy tells Women Fitness that she likes to keep healthy snacks in her purse. That way, she can have something available when she needs an energy boost. "I love snacking though and always carry almonds in my handbag with me if I feel my energy drop."

When it comes to working out, Cundy believes the earlier, the better. She told Women Fitness, "I try to do at least half an hour /40 minutes each morning, light weights, sit ups and squats.. I always go first thing in the morning and this definitely gives me energy for my busy day ahead!"

Cundy is known for her self-confidence, and has never been afraid of showing off her figure. She tells Women Fitness that she maintains her confidence by working on herself, and not comparing herself to other people. "I think everyone has parts of their body they would like to change but my mum always told me not to compare yourself to others. So I don't!! When I'm doing a shoot I'm just comfortable in my own skin and always enjoy it.. Think that shows through in the photos!!"

One of the things Cundy is known for is her charity and humanitarian work. She tells Women Fitness that supporting causes is a big part of her life, and is very important to her. "​​I love doing charity work and it's a big part of my life.. Even when I go to Barbados at Christmas with my family I'm helping to organise the Simon Cowell dog charity event there! Sadly I have had many family members and friends pass away to cancer, cystic fibrosis and I lost my dear Dad to a stroke a few years ago so it's very important for me to give back. I've done many charity runs, hosted auctions and try and get as active as possible to help and give back."
