Personal Training

As a women over 50, Sonia understands the challenges we have all faced. Hence she takes a special interest in Women over 40. If this is you, and you want to transform into a healthier you, Sonia can help. Busy lifestyles, family commitments, work requirements, all of these components of our lives can stop us from being truly healthy.

SRFC Vision is to Transform Your Health, together we can do that through either Personal Strength Training or in a small group. Our indoor training studio is based in Willoughby.

Sonia specialises in Resistance and Strength Training, based on the latest models and techniques. This is ideal as strength training rebuilds the bone cells we naturally lose through the aging process.

Within the gym is wide range of Dumbells, Kettlebells, Bars and free weights along with cardio Cross trainers and steppers. Intermixed with the Resistance Training, many of Sonia clients take advantage of the specialised High Intensity Interval Training (HIIT) workouts. Each personal training session is designed specifically for each client’s focussing on a) their personal goals and (b) any injuries that may present.

We also offer specialised Programs including

HIKEFit – A specific program built around Hiking in Nature,

GOLFFit – Focusing on Stability, Flexibility, Core and Strength . Group exercise classes designed to improve your golf.

STAYFit – Small Group Private classes

TREKFit – program specifically around your up and coming trek

GET YOUR GROOVE BACK – This is all about getting you back to exercise, whether it be through walking or gentle gym exercise.

Please review our specialised program section

Our programs start with a one to one consultation to better understand your fitness goals and what’s important to you and then we create a plan together on how you can get to where you want be and stay there. We will consider exercise, nutrition and lifestyle to transform you into the New You.

Commitment is all it takes to make a difference.. And Sonia will help you make that difference

I recommend anyone who enjoys being outdoors, who wants to maintain or increase their fitness levels should join our HIKEFit Program. Age is no barrier, infact the average age of the Hikers is 48 . It is all about getting you Fit in Nature.

Each Hike is slightly different in terms of KM hiked, ascent of descent, gradients of the hills. Each designed to challenge you and your fitness, however, NOT in a bootcamp sort of way. We walk fast on the flat and at your own pace up hills. This is a two + hour exercise program, which is far more enjoyable than hitting the treadmill at the gym.

If you are about to go on the Trek of a lifetime are you physically and mentally prepared? I have climbed and trekked many mountains throughout the world and have the experience to train you correctly for the challenge ahead. These walks are a great way to being your training journey.

Please register your interest via our CONTACT Page. The full program allows you to gradually improve your fitness. You can join our program at any time and both Men and Women are welcome.

The weekly programs are listed on this website as well as on Meetup and on our Facebook events page. There are limited spots on each walk, before joining it is imperative we understand your current state of fitness.

When attending the HIKEFit program, it is essential you wear appropriate walking gear with stable shoes, sunhat, sunblock, and that you bring plenty of water and a snack. I encourage members to have breakfast beforehand so your body has enough fuel to handle the hike.

If you are worried about your current fitness level, please talk to me in advance and perhaps join us on a ‘GET YOUR GROOVE BACK’ program. Introductory walks to build up your fitness level for the HIKEFit program Our HIKEFit programs will be a great introduction to the TREKFit programs that you will complete when travelling with Trekking Adventures
