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.

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 ageing process.

Each personal training session is designed specifically for each client, focusing on a) their personal goals and (b) any injuries that may present. Our programs start with a one to one complimentary assessment to better understand your fitness goals and what’s important to you. 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

Many of our clients would love to have a Personal Training session or two each week, but just can’t justify the time or money. So to help, we offer SMALL Group Classes. The maximum class size is 8, and the class will always run if there are two participants… so we think of them as SEMI – PRIVATE Classes.

Being a small group, you get the same technical dedication from your trainer as you would in a Personal Training Session. We will modify your exercise if you arrive with any strains of injuries.

The other main benefit of the classes is we are a COMMUNITY. Everyone gets to be friends and we support and encourage each other’s fitness goals. Come and join the fun
