Boundary CrossFit Classes
CrossFit
CrossFit is at the core of what we do at Boundary. Our classes combine strength, conditioning, and functional movements in a way that’s safe, scalable, and effective for everyone. Whether your goal is better health, improved performance, or just moving with more confidence, our coach-led sessions meet you where you’re at - and help you get results.
Barbell Club
Barbell gives you the chance to really focus on improving your lifting technique. This class allows us slow everything down and really focus on the two Olympic lifts, the snatch and the clean and jerk. We don’t worry too much about speed and intensity, instead we spend time working on your technique and form. Every Tuesday 7pm.
Gymnastics
Our Gymnastics class focuses on building the skills and strength needed for movements like kipping, toes-to-bar, and handstand push-ups. Sessions are coach-led, with progressions to suit all ability levels — helping you develop control, technique, and confidence. Every Thursday 7pm.
Saturday Team Wod
Our Saturday Team WOD is a fun, high-energy way to kick off your weekend. You’ll work in teams of 2 or 3, with all workouts coach-led and designed to bring the community together. No need to organise a partner — just show up, and we’ll take care of the rest. Expect a motivating atmosphere and a solid workout to start your Saturday right.
Open Gym
Open Gym gives you the freedom to train on your own terms within our dedicated space. Whether you’re following your own program or working on specific skills, you’ll have access to the same high-quality equipment and environment. Just like our classes, Open Gym sessions need to be booked in advance.
Mobility Flow
Mobility Flow is our hot yoga class held upstairs in the BoilerRoom studio. Designed to improve flexibility, stability, and range of motion, it’s the perfect session to complement your training and help you move better — especially for those looking to enhance their CrossFit performance.
Saturday Sweat
Saturday Sweat is our big weekend workout designed to get you moving. This longer-format class is packed with variety and high-energy individual training — no teams, just you against the workout. Expect plenty of encouragement from our coaches to keep you pushing and start your weekend strong.
Hyrox Endure
Every Sunday we hit a 90 minutes Hyrox endurance session.
