WIARFIT Personal Training Studio

Fantastic experience: As a senior occupational therapist with a deep belief in movement as medicine, I’ve worked with many professionals in the fitness industry, but Will is one of a kind. Passionate, knowledgeable, and truly dedicated, he brings a rare combination of clinical insight, energy, and fun to every session. What sets Will apart is his ability to tailor programs that not only align with your goals but also respect the unique needs of your body. Every movement is intentional, grounded in experience and biomechanical precision. With his laser focus on strengthening where it counts - glutes, core & stabilisers. This is where form meets function, and strength meets mobility — exactly where sustainable health and strength is built. Training with Will isn’t just about fitness gains — it’s about reclaiming confidence, building resilience, injury prevention and enjoying the process along the way. I couldn’t recommend him more highly.

Fantastic experience: As a physiotherapist, I can’t recommend Will more highly. His focus on functional movement, glute and core strength, has not only improved my performance but also helped alleviate some long-standing pain — a brilliant mix of therapy and strengthening. What sets Will apart is his commitment to sustainable fitness. Instead of crash workouts or quick fixes, he helps build a routine that fits into your life and supports your long-term goals. I’ve gained not just physical strength but real body confidence. If you’re looking for someone who understands both the physical and mental sides of fitness, and who genuinely cares about your progress, Will is it!

Fantastic experience: I've been training with Will for just over 3-months now and can categorically say it's been a game changer in the journey to my ultimate health and fitness goals. His fastidious attention to detail sets the scene for every session, and I have gained a deeper understanding of exercise physiology. His immense knowledge and experience are what set his training apart, not to mention his genuine care for all his clients and their overall well-being. Will is a master in perfecting technique and form. He helps you to understand the 'why' in essential, functional movement of the body. In such a short period of time, my lower back issues have ceased, my glutes and core feel stronger compared to a decade of pilates + yoga, and my hip mobility and posture have significantly improved! I'm finally witnessing a glimmer of my true potential. This has been one of the biggest highlights for me. After 3 children and all of life's challenges, I'm just so grateful for the benefits of his specialised training. I've begun 2025 in a strong and transformative way, and it's been truly revolutionary. Thank you, Will. I'm looking forward to what this next chapter will bring...

Fantastic experience: Will is very knowledgeable and very good at adjusting movement so that you are working the right muscle and prevent injury. He’s also very keen to work with my injury and help me recover and rehab. He focuses on functional fitness, uses strength training to help me with my running, hiking and other activities I want to do. The training sessions are always fun and engaging too. Highly recommend him :)

Fantastic experience: I've worked with many PTs but none of them come close to the way Will uses multiple, varied strategies and techniques to achieve not only your goals, but what is best for your body for all round strength, mobility, function and health. I highly recommend Will to anyone. I chose Will as my PT back in 2008 because he had been a professional footballer in his youth (real football, the world game ;) ). I was recovering from hip surgery and Will designed a special strength, conditioning and mobility program tailored for me. This not only aided my recovery, it enhanced and extended my football playing and coaching career.

Fantastic experience: Staying fit and strong is crucial for me. I realised traditional bodybuilding by itself wasn't addressing my aesthetic goals and mobility needs, especially after four lumbar spine surgeries. Will's tailored approach has substantially improved my hip mobility, strengthened my lumbar area and prioritised glutes into my workouts. Will is an excellent strength & conditioning coach and has made a noticeable difference to my mobility, flexibility, fitness and strength. I highly recommend WIARFIT Personal Training Studio.

Fantastic experience: Building core strength, lower back stability and joint mobility which after each session sets me up for the busy day ahead! Technical knowledge of Will's seems endless!

Fantastic experience: After I underwent lower back surgery for a previous injury, Will has carefully focused on building my core strength and stability while mproving my flexibility and mobility. He keeps a very watchful eye on each exercise to ensure I am performing it correctly and always clearly explains the reason for any particular movement and I am certainly reaping the benefits of his expertise. He is very creative with his routines, which makes for an enjoyable session. I have been training with Will for 21 years and find him to be extremely knowledgeable, very professional and dedicated and with a warm, delightful personality that gently persuades and urges me on. I wholeheartedly recommend Will. He is the best

Fantastic experience: Will helped my rehabilitation with a customised strength training program

Fantastic experience: I've been training with Will for the past year and a half. I’m in my mid-40s with a previous ankle injury, so I needed someone who could understand my physical limitations while helping me build strength safely. Will's experience and mature approach have been invaluable - he tailors workouts to work with, not against, my body's capabilities. He brings a positive, encouraging energy to each session, and his sense of humour helps make the hard work enjoyable. Under his guidance, I've made steady progress in strength and mobility, and the training has had a significant positive impact on my mental well-being. His knowledge and professional approach make him an excellent trainer, especially for those requiring injury-conscious strength training. I highly recommend Will as a trainer.

Fantastic experience: I have been training with Will for nearly 15 years and he is the BEST personal trainer out there! He will customise a program based on your individual needs and work with you to get the results you are looking for. 10/10 recommend booking a session with Will in his private space within GoodLife!

Fantastic experience: I have been a loyal client of Will Arias at WIARFIT since 2006! That makes me old but I’m as fit and strong now as I was 18 years ago. From week one I noticed improvements in my core and glute strength. My balance and agility have improved and Wil has tailored exercises to improve all the sports I have done in this time: tennis, bike riding and now distance ocean swimming. The program I have followed and has been tailored for me is truly sustainable and allowed me to maintain strength and vitality. He is passionate about the craft of keeping fit, great company and has a terrific private studio.

Fantastic experience: I had a herniate disc surgery 2 years ago, and Will helped me to gain strength in my core and avoid more future lesions. I feel more confident about a lot of exercises that before I wouldn't even think about . Really grateful for his patience and commitment

Fantastic experience: We had our first session in 2015, and I never looked back since! I learned how to train properly, my core conditioning and glute strength apart from learning how to periodise my program through the year to avoid injuries and burnouts. I look forward to keep improving my fitness mindset, strength and aesthetics while being coached by Will at the wiarfit personal training studio, where I find all why I need for my tailored sessions. It is a great location. It’s worth every minute of commuting to Armadale.

Fantastic experience: I couldn’t ask for a better coach than Will! He is passionate, so knowledgeable and takes the time to ensure every client is getting exactly what they want and need. He educates you about how to adjust your exercise to not only get the body you want but also to avoid any injuries. I’ve been training with Will since 2014 and it’s not only resulted in a body I’m happy with and proud of but also increased my confidence (I’m not nervous to step into a male-dominated gym anymore!) and strength. Will is passionate about what he does and really thrives off seeing his clients succeed and reach their goals. Training with him has been so beneficial to my fitness, strength, and enthusiasm towards working out. I wholeheartedly recommend him as a trainer!

Fantastic experience: I have been training with WILL for almost four months. I lost three kilograms without controlling my diet. This month I started to control my diet. I hope I can lose more weight. WILL is a very good coach, he is very professional, humorous, easygoing . Oh, by the way, I have the problem of lower back pain. He also formulated some training for me to deal with this problem. I feel much better recently and I am very happy!

Fantastic experience: As an elite endurance athlete looking to maximize strength and mobility, Will has provided me with over 15 years of exceptional guidance and care on my never ending quest to stay strong and healthy through workouts that are always challenging and fresh. His passion to bring the best out of his clients is evident in every session he takes. There is no one better to turn to for strength and conditioning.

Fantastic experience: Will has a deep understanding about the science of human body performance while also incredibly experienced. Will’s profound background in training allows him to utilize his knowledge to tailor design various workouts that helps me boost the speed of achieving my personal goal. After some months training together, not only I’m much stronger, but also wanting to spend more time in front of the mirror everyday. I'm exceedingly happy with the results that I get, and I just need for more. Also, I need to mention that because I had the past experiences of training with some of the very best PTs in Beijing China, so over the years I’ve become very selective about choosing the right personal trainer. Will is on par with any top tier PTs that I had the privilege to train with before, and I consider myself so lucky to have discovered someone as good as him in Melbourne. I want to recommend Will’s studio to all of those who take training as a lifestyle and determined in making a change.
