Elevate Your Strength. Master Your Body.

Train with purpose in an environment built for progress, precision, and performance.

We are not just a gym, we are a lab.

A place where strength is engineered, movement is refined, and human performance is elevated. Every detail of The Cali Lab has been purpose built to create an exclusive environment where bodyweight training, mobility, skill, and athleticism are developed with precision.

More than a fitness facility, The Cali Lab is a private community of individuals committed to mastering their potential.

This is where limits are tested, progress is measured, and excellence is the standard. Every session is an experiment. Every challenge is an opportunity. Every achievement is earned.

The Cali Lab isn’t a gym. It’s a lab for human performance. Welcome to Corby’s home of elite calisthenics.

Frequently asked questions

Where in the indoor market are you based?

If you come in the front door of the indoor market between 9-5pm Monday to Saturday you simply follow the path around like a horseshoe keeping to your left and you will find us at the end in room. If you come to one of our classes outside these hours you will be let in the door round the back of the building on Elizabeth Street.

Are parents allowed to stay during the class?

For safeguarding reasons, guardians are not allowed to stay inside the gym during sessions. However, you’re welcome to relax in the seating area outside the gym. To ensure a secure environment for all children, our team will be monitoring the entrance at all times, and we kindly ask that parents follow a drop-and-go system. That being said please ensure your child is happy and confident enough with this.

TESTIMONIALS

'Since starting at The Cali Lab in October 2025, I have loved every session. Everyone is made to feel comfortable and welcome, and the atmosphere is always friendly and supportive

Coach Terry is amazing. He pushes everyone to be their best while making sure each person feels included and supported. Regardless of your fitness level, you're treated with the same respect and encouragement.

I would highly recommend The Cali Lab to anyone, whether you're a beginner feeling nervous about joining a gym or someone who is already passionate about fitness. There is something for everyone, and it's a great community to be part of!'

'The Cali Lab is an elite level gym and community space. Open to people from all backgrounds, ages and fitness levels. Terry is extremely knowledgable about fitness, nutrition and life. This is a community, other members are welcoming from day one and are happy to politely give you advice and share knowledge. Whoever you are there is place for you, as long as you come with respect you will thrive.'

'I have been going gym on and off for 10+ years now and nothing compares to this gym and the coaches. The workouts are good and challenging for all levels and aspects of training and fitness. Anyone I have been accompanied by during workouts or classes have been mega helpful and welcoming. Terrys 1-2-1’s have been a major part in me developing as much as I have, fills you with a lot of confidence and gives you that extra bit when you feel like it ain’t there, I have fallen in love with the calisthenics side of things here and seen a massive progression in strength and body shape, shredding down and changing my outlook on health and longevity.The only words to describe is for me is basically LIFE CHANGING. The most warm and welcoming gym I highly recommend.'
