Can I attend more than two sessions per week?

Absolutely yes. If you’re attending more than two sessions per week, it’s crucial to incorporate additional health practices into your routine. Prioritize getting a full 8 hours of sleep each night. Consider adding supplements to support your fitness journey (Colleen can provide guidance). Stay hydrated by drinking plenty of water to nourish and replenish your muscles. Additionally, ensure you’re consuming enough green leafy vegetables and fibre to nourish your gut flora and maintain a strong immune system.

Colleen offers all members complimentary personalized eating plans, supplement suggestions, and holistic health guidance.

Explain an Isoflex session. What does it entail?

Each week, Colleen meticulously crafts two distinct sessions. Her process begins with selecting the perfect music, setting the tone for the entire session. Next, she designs a tailored warm-up routine focusing on the upcoming strength training exercises. She then creates mindful stretching sequences, aligning with the targeted muscle groups. The breathing techniques are intricately woven into the planned contractions and stretches, enhancing the effectiveness of each movement.

To conclude every class, she guides a tranquil 10 to 15 minute relaxation and meditation session, allowing you to unwind and rejuvenate both body and mind.

Do you offer one-on-one sessions?

Yes, we do.

To enhance your experience further, we recommend wearing socks during your session. If you prefer to practice barefoot, it’s vital to ensure that your feet are clean before stepping onto the mat. This not only maintains hygiene but also ensures that the mats stay clean and always look new.

Additionally, we advise bringing a face towel to rest one your mat during practice. This precaution prevents makeup residue from transferring onto the mat,

How does payment work?

Unlock Your Potential with Isoflex’s Commitment and Accountability System

With over 25 years of experience in the fitness industry, I’ve learned that commitment and accountability are the keys to success. At Isoflex, we’ve implemented a unique system that ensures our clients stay committed to their fitness journey while holding themselves accountable for their progress.

Here’s how it works: Clients pay for their classes on a monthly basis, but before committing, they have the opportunity to attend two free classes to experience the Isoflex difference firsthand. Once enrolled, the first month’s fee is adjusted to reflect the deduction of these two complimentary sessions, making it a cost-effective way to start your fitness journey with us.

By paying your class fees in advance, you secure your spot in class, ensuring that it’s always available to you when you need it. This commitment not only motivates you to attend regularly but also helps you stay on track with your fitness goals. On our Isoflex journey together, I not only guide you through workouts but also get to know YOU personally. Your unique body, movement patterns, strengths, preferences, and personality all inform the tailored experience I create for you. With your monthly commitment, I’m able to support your progress, ensuring that each class nurtures your growth and benefits you holistically. Together, we’ll thrive and elevate every aspect of your fitness journey.

We understand that life can be unpredictable, which is why we offer flexibility for missed classes. If you’re unable to attend due to illness or vacation, you can make up for lost classes at your convenience. With our accommodating system, you’ll never miss out on valuable workout sessions, ensuring continuous progress towards your fitness objectives.

What age groups are most popular at Isoflex?

At Isoflex, our clientele spans a wide age range, typically between 40 and 85 years old. Over my 25 years of experience, I’ve found that age is never a barrier to success at Isoflex. Our workouts are designed to accommodate individuals of all ages and fitness levels, ensuring that everyone can build strength and flexibility. We offer alternatives and improvisations for exercises, and since Isoflex incorporates isometric strengthening, there are always options available to suit your needs.

Can I do Isoflex if I am pregnant?

Absolutely, Isoflex is not only safe but also highly beneficial for women who are planning to become pregnant or are already pregnant and may feel unfit. In my own experience, I continued to engage in 12 hours of Isoflex per week throughout my pregnancies in South Africa, teaching classes right up until the very day I gave birth to both of my children. It was a testament to the effectiveness and adaptability of the program.

Throughout my career, I’ve had the privilege of training numerous pregnant women who shared the aspiration of being strong and prepared for motherhood. It’s an honour to support them on their journey. Motherhood is physically demanding, requiring hours of holding, bathing, nursing, and lifting your precious baby every day. Being physically strong and capable enhances the joy of motherhood and helps you navigate these tasks with ease and enjoyment.

It’s worth noting that during pregnancy, the hormone relaxin softens the body’s ligaments, which can increase the risk of injury. This is why having strong and healthy muscles is crucial, especially since relaxin remains in the body for up to 12 months after giving birth. Isoflex focuses on building strength and flexibility, making it an ideal fitness choice to support you during and after pregnancy, ensuring you’re equipped to embrace motherhood with confidence and vitality.

May I contact you personally if I have any questions or concerns?

My personal message to you:

In this sacred journey together, know that you are never alone. If any concerns weigh on your heart, may you reach out to me personally. Your well-being is my priority, and I am here to listen, support, and guide you through any challenges you may face. Life’s twists and turns are inevitable, and I understand that unexpected circumstances may arise, disrupting your class attendance without notice. Rest assured, I am ready to accommodate you with understanding and compassion. Your joys are my joys, and your sorrows are my sorrows. Together, we walk this path, united in spirit and strength. I am here for you, always.

Colleen, a beacon of inspiration in the realm of fitness and holistic well-being, embarked on her journey in Human Movement Science at the University of Pretoria. Fuelled by her passion for empowering others, she laid the foundation of Isoflex in her father’s garage during her final year of studies. What started as a mere trial soon blossomed into a lifelong dedication, as people embraced her innovative approach to fitness with enthusiasm and commitment.

Over the course of two decades, Colleen cultivated Isoflex into a thriving enterprise, establishing her own studio and disseminating her expertise through instructional DVDs and franchising opportunities. Drawing from a diverse array of disciplines including Pilates, Yoga, Karate, Modern Ballet, and more, she meticulously crafted workouts that seamlessly integrated the most effective elements of each practice into a concise 60-minute session.

Her unwavering dedication to her clients’ well-being goes beyond physical transformation; it’s about fostering confidence, strength, and joy in every individual she encounters. Colleen’s ultimate goal has always been to empower her participants to not only achieve their fitness goals but also to embrace life with renewed vigour and vitality.

Despite the challenges of relocation, Colleen’s resilience and passion remained undiminished. From South Africa to Auckland, she continued to pursue her dreams, opening Isoflex studios wherever opportunity beckoned. Each setback only fuelled her determination, leading her to the realization of her long-cherished dream – the Silverdale Isoflex studio.

As she embarks on this new chapter, Colleen’s unwavering commitment to improving the quality of people’s lives remains steadfast. With every class, she aspires to instil a sense of empowerment, confidence, and joy, enabling her clients to fully embrace life’s adventures and pursue their passions with vigour.

Today, as she prepares to unveil the Silverdale Isoflex studio, Colleen stands as a testament to the transformative power of resilience, passion, and unwavering dedication. Her journey serves as an inspiration to all those who dare to dream, reminding us that with perseverance and belief in oneself, anything is possible. Join Colleen on this extraordinary journey towards holistic well-being, where each step brings us closer to realizing our fullest potential and living life to the fullest.
