About Our Sessions:

Lean & Mean – this session is designed to tone, give you definition and also help with fat loss. Using weights we combine a mix of HIIT cardio in the session to give you a great calorie burn while toning your body with weights.

BeachFit – A High Intensity sand session on Monday’s held on the beach or in the sandhills. Hard work but loads of fun, low impact on joints and so very effective!

Strength – Bring your muscles with you to this one – using heavier weights and lower reps, we are building strength, lean muscle to aid with fat loss, and getting your heart rate up without cardio.

Boxing & Kickboxing – Our boxing sessions are a great cardio workout using focus pads – high intensity and fun. Our Kickboxing sessions are a  great leg and butt workout. Using Kick Shields, you’ll still need your boxing gloves for this one, but definitely a great lower body workout designed to get our heart rate up, have fun and burn some serious calories.

Strength, Core & Stability

    – A session designed to tone muscles, increase stability and aid in injury prevention by strengthening your core and stabilising muscles, challenging your balance and agility. Great for Runners, but everyone in general.

Smash – Cross Training

    – An all over body workout that is high intensity cross training. This session is a mix of circuits and various cross training exercises and equipment. A great calorie burn.

Yoga – Power yoga and chill yoga – our amazing instructors will guide you through sessions helping to improve flexibility, strength and calming your mind.

Saturday Trail Runs – An casual run most weeks getting out and exploring the trails. If we have events on the horizon then we will also hold event specific sessions. These sessions are aimed at current events clients are training for. Course-specific training locally and on the actual course where possible to get you race ready! All are welcome to attend, whether you are doing the race or not.  Come along for all or part of a session. We take you to some beautiful new places, so come join us! ($25 pp for non-members)

And of course our Running sessions include, well, running! All sessions will cater to all levels of fitness, while giving you a good cardio workout and one of the best calorie burns. Great to improve overall aerobic fitness and improve your general health and if you are after performance improvements we cover that too.

My family and I owe a lot to Simone, if she wasn’t such a good trainer I know I would have given up years ago and my health would be suffering, instead I am living my life and enjoy exercising.

Simone has the perfect combination of caring and endless energy to help us achieve our goals and this has also developed into a mentoring relationship in which we trust. It was evident from our first meeting that Simone was concerned about our long term health and well-being which has resulted in our improved fitness and dietary awareness which has assisted us in achieving goals that Simone has helped us set along the way.

Simone’s dedication and knowledge wasn’t only a program of multiple weekly outdoor group sessions in addition to a weekly PT session it was more than that. Simone’s program was a combination of calorie counting & meal plans, emotional support and goal setting both physically and emotional.

She has created a fun, friendly atmosphere in all her classes .I have made many life time friends because of this. No two sessions are EVER the same. Her time and attention to detail is flawless.


‘I have been training with Simone Hayes at Energy Fitness Gymea for approximately 3 years and she has definitely bought out the best in me.

Three years ago, I was NOT motivated, I exercised because I had to, and I looked for and believed all the excuses I came up with to not exercise or try new things.

Today, I am a different person! My lifestyle is so much healthier, I am healthier, I am stronger and I am 10 kilos lighter than what I was 3 years ago.  I am entering events I never dreamed of, let alone compete in.  My confidence just gets better and better, and for this I have Simone to thank.

Simone has a passion for sharing her knowledge of what it takes to lead a healthy lifestyle. She has extensive  knowledge in all areas of fitness, health and nutrition – and can lead anyone into a better and more healthy lifestyle.

Simone’s classes are hard! However, the classes cater to all levels of fitness.  Three years ago, I struggled to run 3 km, now I am running 10 – 15 km three times per week, and loving it.

Simone is incredibly motivating, and she leads by example. Being a busy Mum herself, she is inspiring and incredibly motivating to all her clients.

Not only am I fitter and leaner these days, additionally through Simone’s classes I can honestly say that I have met many life-long and fantastic friends.  The friendships I have formed have also been a huge bonus for being part of Energy Fitness, there are always jokes, good laughs and, if you choose, a nice coffee after classes with some great people.’


Hi Simone,

I just wanted to send you an email to thank you for the last ten weeks.

Eighteen months ago I was 20kgs heavier and getting over numerous operations and my body was full of drugs from my treatment. When starting beach fit I had little confidence in my ability and I was struggling mentally and physically to do any exercise.
So starting beach fit was a massive challenge for me, I am thankful that you made it so easy for me and made me feel very welcome. To go each week and be the slowest person could of been a real challenge and could of made me quit, but at no time did you or anyone else do the training make me feel like I was holding them up. This is a credit to you and everyone doing beach fit as I have done other challenges and was made to feel totally out of my depth.

I just wanted to thank you again for helping me get on the road back to being my old self. I have not felt this good mentally and physically for a long time.

You are what every trainer should strive to be, you truly are an inspiration.

Thanks again

Hi Simone

Thanks for a great program. It was hard work but very rewarding and I was really happy with my results at the weigh-in. I’m amazed at what my body can do and I thank you for your knowledge in knowing how far to push me. It makes me really excited to think that we will be fit and active Grandparents for our family hopefully in the long term future.

Living at Engadine we rarely go to Cronulla so it is a great opportunity to get down there, and at the most beautiful time of the day too. That in itself has been a revelation for me and well worth the early starts.

So yep, sign me up for Feb 2016 for Wednesdays.

Enjoy your well-earned break and I’ll see you soon.

Completing Energy Fitness’ Winter Meltdown Challenge in 2015 was one of the most fun, challenging and mind-blowing experiences of my life. If you had have told me when I started the challenge that in 10 weeks’ time I’d be crossing the line in a half marathon I would have laughed in your face! But that’s the whole point… Simone has created a program that sets you up to physically and mentally achieve things you never imagined possible.

With the yum recipes, the 10 week training plan, variety of challenges in some truly beautiful outdoor settings, the comradery, photo-sharing and laughs from the community of ‘Challengers’, as well as Simone’s unwavering personalised encouragement and support, it’s no surprise that people come back and complete the Challenge each year to stay motivated and keep up with their training during the chillier months.

It’s been nearly a year now since I completed the Challenge and I use what I learned during those 10 weeks on a daily basis. Once you put in the work, learn the lessons and achieve what you want to achieve, you don’t have to think about measuring portion sizes or counting calories for the rest of your life – you know how to put a good meal together and you know when you’ve done enough to enjoy the good things in life. Like the Cocktail party at the end of the 10 weeks!

If you’re undecided whether or not to sign up… just go for it. You won’t regret completing the challenge but you might regret missing out!

……Then one Sunday in July after finishing a fairly modest distance in a track ultra, one where there are no qualifying criteria, just rock up and see how many laps of an oval you can do in 48 hours, a certain Simone Hayes who I had met in Jindabyne in 2021, said to me: “See you at Coast to Kosci”.
I scoffed and said: “I will never qualify.”
She said: “Mate, throw your hat in the ring, you never know.”
And that sent me back to the website, where I stumbled across the words “directors’ discretion” and “persuade us so we can’t say no.”
The next few days I spent desperately trying to come up with sufficient motivation to persuade the Race Directors that a below average back of the packer, with a little bit of pedigree and grit might be worth a punt.
I wrote an essay that accompanied the formal application and as I pressed send I imagined Mick Campbell, an Aussie Scotsman with the biggest heart and sharp wit, saying to his Co-Race Director, Greg: “Look at this wee fella, Zlotnick. He seems to think this is a creative writing competition, not a serious athletic endeavour.”
I shat myself a few weeks later when I got the call: “We are pleased to invite you.”
Suddenly it was on.
And so began the fine tuning of my haphazard run/walk routine to be ready to stand on the beach at Twofold Bay in December.
It turns out I was ready to toe the line and, as it transpired 3 turns of the 24-hour clock later, to scrape home a finish.
First thanks go to Simone Hayes who I asked to coach me. She is one of the most formidable women I have met.
She scares me in a nice way.
She has superb running pedigree, as a participant and as a volunteer in the running community. She is actually just a superb human being.
Having Simone introduce some science and balance and rigour and discipline into what passed for my previous training was a real eye-opener.
She was a quiet and subtly strict motivator.
A man-manager and psychologist par excellence.
She has an eye for detail and monitored me carefully, adapting my training as I responded to the two weekly programme she would send me.
I looked forward to her Monday emails to see what surprises she had in store for me for the next block.
She taught me to trust the process in the physical training; and at the same time she got right into my head to allay doubt and uncertainty and utterly believe that I can do this.
Absurd as this may sound, she made the hard training fun.
I left the start line repeating Simone’s mantra to me over and over: “Patience, accept the discomfort, all day pace.” It worked.
