Sarah relies on EatUP, a meal delivery program, to ensure healthy eating. "I loved EatUP, and I've tried a few different meal prep companies, again just to make it easy for work, and by far they were the tastiest, most filling meals," she told Ultimate Performance. "The benefits of using EatUP is it takes away that element of having to do meal prep, and if you're really struggling for time, and I know some people will be, you don't have to think about the meal prep. You don't have to think about the macronutrients – they're tailored to you. What you need is in those meals for the day. Literally, all you have to think about is just heating them up." She adds that it also eventually helped her to prep her own meals. "Once I got into that, I was able to start meal prepping myself. It also gives you ideas about what you can do and what you can be eating, so by having those EatUP meals, it gave me ideas about where I could go and what I should be eating, and portion size. It just shows you that there is variety and that you can have exciting, interesting, tasty meals, and that you don't just need to stick to boring foods."

Sarah whipped herself into shape with the 12 week Ultimate Performance program. "The training online has been great. It's been really easy to follow. You get a tracker the minute you sign up where you fill in what you've eaten and what training you've done and what weights you have used. Your trainer is constantly looking at that and guiding you and picking up on things if you do something wrong or if you eat something you shouldn't. It's been super easy. You've got that support there all the time," she said. 

Sarah maintains that eating small portions is the key to her diet. "It's really obvious the things that you end up eating. It's not rocket science at all. It's more about portion control and getting into that routine of measuring out rice or sweet potato. Then once you get into the rhythm of that, it becomes really easy and you can visualise and see what your portions should be," she said. "There's a huge list of foods that you can have. You're in no way restricted and there's loads of variety. I've still managed to have the odd night out too."

"Weight training has been the main thing I've done over the last 12 weeks and it's been that that has been the most effective for fat loss and improving strength," she told Ultimate Performance. "I've weight trained and increased my weights and still maintained being feminine. I think women worry about weight training and worry about lifting heavy weights, and actually it's something you should do and something that your body will embrace."

On National Fitness Day, Sarah celebrated with an exercise session. "Working out for me means being a good role model, looking after my physical and mental health, self care, increased energy, feel good hormones, pushing my limits, staying consistent, challenging myself and feeling strong," she captioned an Instagram post. 

Sarah's exercise class of choice? "I love my pole classes, everyone is so supportive of each other and genuinely will each other on to get better, overcome challenges and be strong…," she captioned a recent post.
