About Slim Force Heidelberg

Have you tried everything from bootcamps to mainstream gyms and never feel quite like you fit in?
Worried about people looking at you and wondering what you’re even doing exercising?
Sick to death of all the restrictive food and exercise regimes out there that you can’t possibly keep up with?
Just want somewhere you can go and exercise in comfort without feeling judged about your weight or body shape?

Slim Force’s Heidelberg personal training studio might just be the answer you have been looking for. While we welcome people of all shapes and sizes, our personal trainers specialise in helping get plus size beginners off to the best possible start with their fitness.

Located on St James Road, just off Rosanna Road, our studio is quiet and away from the hustle and bustle of Burgundy Street. Our training studio is also private meaning people walking by won’t be looking in through the windows at what is going on inside. Even parking is a breeze when you come to Slim Force Heidelberg.

We aim to create an environment that is truly welcoming and non-judgmental of everyone who walks through our doors.

Our Core Beliefs

  • Fat shaming, any body shaming for that matter, is never okay.
  • Your weight does not determine your fitness. Not by a long shot.
  • Big bodies can do lots of things – regardless of where you are starting.
  • You deserve to be happy and feel good about yourself NOW, regardless of your current size.
  • Your current situation only determines where you are starting from, and not how far you can go.

I highly recommend Slim Force Studio for all your training requirements. Rhonda is an awesome trainer, very motivated and knowledgeable.. I started off with the small group sessions once a week and progressed to, two PT sessions per week. I am very happy with the results we have achieved, the hard work is paying off.

I’ve been training with Kate for a long time now. She has always got the best from me, but now we’re training in the brand new studio, my fitness routine and enthusiasm has gone to a whole new level! The equipment is so versatile and opens up a huge variety of options for me to be able to work around my ongoing knee injury. The studio is spacious and private and I really feel like a VIP client. I’m well on my way to becoming ninja fit, and I’m loving it!

I’ve been going to Slim Force for 2+ years and love it. Exercising is never fun when you are not enjoying it but I always have a great time. Rhonda is fantastic. She is a tough trainer but very supportive especially if you have injuries or pain in certain areas of your body. If its a hot day, she will always provide a cold towel or drink. If you have back pain, she will train you in other areas of the body. If you are too tired from a long week, she will give you exercises that pump you up. I always leave the gym feeling like I can take on the world. Im not the easiest person to train and am a self-titled “Queen Whinge” but you always take it on the chin. Thanks guys!
