“Fresh perspectives with amazing results.


My experience with Sian’s training program was nothing short of exceptional. Utilizing her wealth of knowledge combined with real world experience Sian created a training plan for me that put me out of my training comfort zone and gave me new found balance, strength and stability. The program was targeted at riding and racing and very much increased my strength but also enjoyment of riding with better strength in my upper body, core and legs. The training plans fitted into my life schedule, were super easy to follow when training remotely and brought new ways of thinking to the way I trained. Any rider will benefit from a structured training program from Sian and I put the challenge out to everyone to see how much they can improve when dealing with a true athlete and professional. “

"After making the decision to go #fullenduro, I invested in a home-gym program with Sian. I had done some consistent gym work before, so was curious to see what could be added to my workouts. After the first couple sessions, I realised how much of my body I was underutilising and how weak I really was! The gains came slowly but surely with some perseverance and encouraging guidance from Sian. After a few months on a program, there are noticeable improvements in my technique and stamina on the bike. I work fulltime and ride nearly every day, and Sian's program is perfectly tailored to my time and equipment restrictions at home. The workouts are mtb-specific, something you won't find from your average gym PT or online guru. Commit yourself to a program with Sian and you'll reap the rewards out on the trail."

Sian’s well-known talents as a rider and competitor are complemented by a natural ability for teaching the skills of mountain biking. The lessons are clear and well-structured, with detailed but easy to follow demonstrations of technique. Sian knows just how far to push you in each session, so that you leave with the real feeling of being a better rider every time. Above all, the sessions with Sian have increased my confidence and overall skill. I would recommend the lessons to anyone who wants to improve on nearly any aspect of mountain biking.

I got given a coaching session for my birthday. I’ve watched Sian ride at Thredbo and followed her achievements on Instagram. Sian made the experience interesting and was really friendly.  Sian  was genuinely interested in helping me achieve my goals.  I throughly recommend a lesson, if you want to improve yourself.  Her motivation to get you to raising the bar is awesome. Thanks heaps!

Sian’s monthly programs are honestly probably the best thing I’ve purchased to help with my riding. The structure is super easy to follow, set to your personal life and structured to your discipline as a rider. I used to have a super slack program that I would just change or skip days cause I could, but I feel this gives me the drive to put the work in and get stuff done, which I love about it. It also just fills up the day up so don’t get distracted as easily if you are that type of person. I also highly recommend at least 2-3 gym sessions a week, I find it helps you focus on the other aspect of riding and that putting the hard yards in the gym, make you miss your bike in a way, allowing to get pumped for the next time you ride your bike. I now it did for me. 

Sian is super nice and humble, she makes you feel welcome and comfortable, always there to help for advise or showing you movement. She puts the things you want to train at the core and helps you improve on that and encourages you along that process. Improvement is on her mind for you and improvement you will get!  

I highly recommend these programs from Sian, I saw significant improvements in the first month of doing the program. 100% worth your time, you will definitely see a change in fitness, and improvement on the bike. Highly recommend!!

I've been MTB riding for about 18 months, and had hit the point where I needed some coaching to be a more efficient rider. I also wanted to learn how to jump, drop and pump. I was gifted a 1hr coaching session with Sian for my birthday and after some pre-coaching engagement, Sian knew how to use the 1hr session so I would get the most out of it.
Sian is observant and provides frank feedback. She is able to articulate clearly how to perform the moves and then will also demonstrate them.
Since my one on one, I've had a couple of group sessions and have seen immediate results. I am faster, thinking about my turns, pumping instead of peddling, attempting the jumps rather than rolling them and can drop off rocks with a hell of a lot less fear. I highly recommend a one on one with Sian if you'd like to become a more efficient rider.

"Sian A'Hern's experience in mountain biking and her commitment to training makes all programs engaging and 100% worth while. I can't recommend Sian enough to anyone looking to excel in their fitness and mental strength"

"Sian has been amazing with all the training, i haven’t even completed a full year of training and I have made large improvements in my results which I could have never achieved on my own. The programs are specially made to fit your lifestyle and your weekly schedule, which is awesome. The variation in excersizes is great because it doesn’t get repetitive. I love Sian and she is honestly a motivation for me to make gains and get on my bike and go shred"

"After a MTB lesson with Sian and my mates at Stromlo my Dad agreed to pay half for an on-line training program, and I paid the other half and do chores. I love Mountain Biking and competing DH and Enduro and have raced heaps this year (even with COVID). Sian is really good with kids, she understands that we have heaps of school stuff and that we hate riding uphills! She has made monthly MTB programs for me that have really helped me get bike fitter, bike stronger and less out of breath (google = anaerobic fitness). I like that she checks in on me and gives me encouragement and helps explain why I need to do these exercises to become a better rider. Mum does F45 and she thought I could just do her F45 program, but it's not the same, Sian understands what it takes to be a Champion MTB rider, and she creates and coaches me for this purpose."

"Having only been getting a program with Sian for 3 months, have found myself already getting strong and fit. My confidence on the bike has increased significantly due to my gain in strength. Sian has helped me through my adrenal fatigue which I am so thankful for. Thank you Sian. Looking forward to what's to come."

Sian Ahern has been virtually coaching me this year during Covid-19 to help build my strength and confidence in the mountain biking world.

Sian is motivating and keeps the training program interesting with new ideas with training regimes. She has helped condition my body with strength and endurance sets which has greatly improved my riding and also my fitness level.


It was great to finally be able to ride with Sian at this years Thredbo gravity series in Dec 2020 where she coached me through to a podium finish in the under 17s as 2nd place.

I would highly recommend Sian as a coach, she is a great mentor, great motivator and it has been a great experience for me.

Sian Ahern has been coaching me online for almost 6 months, helping me to increase my strength and fitness, and in turn increase my riding skills and stamina.

I also had a one on one coaching session with Sian. She was super friendly, and helped me with body positioning and skills on my bike. From then I practiced the skills and techniques she had told me and now find myself a more confident and stronger rider . Sian has sent me monthly training programs for on the bike training, she is always ensuring she mixes things up, keeps it interesting and fun.  She is super motivating and has driven me to put in the work.

I am excited to race again soon and see the difference in my results since training with Sian. Don't think twice though, book in with Sian, you won't regret it!
