“I came into this challenge thinking I understood nutrition, but quickly realised I didn’t. The team at TSD are next level and genuinely know their stuff. Learning how to properly fuel my body has completely changed how I feel day to day, with more energy for long shift work days, training and everyday life.
It wasn’t always easy, especially breaking old habits that had been with me for years, but the support and guidance made all the difference. I’m incredibly grateful for the experience, and for the first time in a long time, I feel comfortable and confident in my own body again.”

“The mental side of this challenge has been more beneficial to me than I thought it would be, finding bad habits that I didn’t know I had and correcting them has been so eye opening to me! The TSD team made this such an easy and smooth process with constant support and guidance. I wasn’t happy with myself and how my body looked prior to the challenge but now I’m proud of my mind and my body.
It wasn’t always easy, especially with a 4-month-old and life’s curveballs, but the reminder to control what I can control made all the difference. Cass was my rock throughout the challenge, and I feel so lucky to have had her by my side.
I’m excited to keep growing and learning with TSD.”

Joseph, Challenge Winner
“This challenge has had such a positive impact on my postpartum journey, especially my mental health. It’s such a challenging time and I definitely felt like I lost myself, but this has given me a sense of normality and helped me start finding myself again.
I’ve learned how to properly fuel my body for workouts and breastfeeding, and that consistency over perfection is what really matters.
I feel more confident, my self-talk is more positive, and I’m so grateful for the coaching and the support from others going through the same stage especially my husband — it’s made me feel so much less alone on this journey!”
