STRENGTH IN NUMBERS
POWER IN COMMUNITY
CrossFit TwentyThree was born from a passion for fitness and a commitment to fostering a supportive community. Our mission is to inspire and empower individuals to lead healthier, fitter lives by sharing our love for exercise and creating an environment where everyone feels welcome and motivated to achieve their best.
INTRODUCING
THE MOTHERHOOD PROJECT
Strength for Motherhood and Beyond.
We’re proud to introduce The Motherhood Project (TMP) our brand new postnatal strength and conditioning programme.
Designed for women returning to exercise after pregnancy, TMP combines expert-led coaching, progressive strength training and a supportive community where you can rebuild confidence, regain strength and bring your baby along too.
Whether you’re taking your first steps back into exercise or looking for a community of local mums on the same journey, The Motherhood Project is here to support you every step of the way.
About Your Coaches
At CrossFit TwentyThree, our coaches are more than just great trainers, they’re educators, mentors and teammates. We coach with purpose, using simple and smart programming, clear instruction and genuine care to help every member move better, train harder and keep making progress, whatever their starting point.
14 DAY INTRO TO
CROSSFIT @ CF23
At CrossFit TwentyThree, we believe in giving new members a comprehensive experience right from the start, which is why we don’t offer free trials or foundations courses. Instead, we provide a 14-day unlimited trial. This trial period offers a thorough introduction to CrossFit, allowing you to fully immerse yourself in the varied and dynamic workouts that define our program. Therefore you’ll experience firsthand the diverse and constantly varied nature of CrossFit, making it the best way to sample everything we have to offer. You will also have unlimited access to our dedicated open gym space “The Workshop”.
