A power rack can be the centrepiece of a home gym, giving you a dedicated space for exercises such as squats, bench presses and other barbell movements. But not every rack suits every training space.
The right choice depends on how you train, how much room you have, the weight you plan to lift and whether you want to add attachments later.
Before buying a power rack, there are several things worth checking. Here's what to look for when choosing one for your home gym in Australia.
1. Choose the Right Type of Rack
Start by deciding which type of rack suits your training and available space.
Full power rack
A full power rack typically has four main uprights surrounding the lifting area. When fitted with suitable safety bars or other approved safety components, it provides a contained space for exercises such as squats and bench presses.
It's worth considering if you regularly lift heavy weights, want a dedicated strength-training setup or plan to expand your equipment over time.
Half rack
A half rack generally has a more open design and may take up less floor space than a full rack. It can be a practical option for a garage gym or a smaller training area.
Check the available safety features and the manufacturer's installation requirements before choosing one.
Rack with a cable system or Smith machine
Some racks combine traditional barbell training with additional equipment, such as cable pulleys or a Smith machine.
These combinations can provide more training options in one setup. However, they may cost more and require additional space, so compare the complete dimensions and features before deciding.
2. Check the Frame Construction
The frame affects a rack's rigidity, durability, and suitability for your training.
Look at the following specifications before comparing models:
-
Upright dimensions: Check the width and depth of the steel uprights.
- Steel thickness: Compare the stated material thickness rather than judging strength by appearance.
- Hole spacing: This affects where you can position J-hooks and compatible attachments.
- Finish: A suitable protective finish can help maintain the frame's appearance.
- Overall construction: Consider the design, connections and manufacturer specifications.
For example, the ONYX Power Rack uses 75 × 75 mm uprights made from 3 mm steel, with 17 mm holes spaced at 50 mm intervals.
These specifications provide a useful starting point for comparison. However, frame dimensions alone don't establish a rack's overall safety or load capacity. Check the manufacturer's ratings and installation instructions as well.
3. Look at Safety Features
Safety should be a priority when choosing a power rack, particularly if you train alone.
Depending on the model, useful features may include:
- Adjustable J-hooks for positioning the barbell.
- Safety arms or other approved safety catches.
- Secure attachment points.
- Stable construction and appropriate anchoring provisions.
Make sure the safety components suit the exercises you intend to perform. For example, the setup needed for squats may differ from the arrangement required for bench presses.
Check how the safety components adjust and whether they are included with the rack or sold separately.
Follow the manufacturer's instructions for assembly, anchoring and use. Never exceed the specified load limits.
4. Consider Weight Capacity
A rack's stated weight capacity is important, but it should be considered alongside its design and intended use.
Think about the heaviest loads you currently lift and whether you expect those loads to increase. Then compare the manufacturer's rated capacity with your requirements.
Also check whether the specifications distinguish between different components or types of loading.
Don't assume that a rack with a higher advertised capacity is automatically the best choice. It still needs to fit your space, support your training and include appropriate safety features.
If you're unsure which model is suitable, ask the supplier to confirm its specifications for your intended use.
5. Measure Your Home Gym Space
One of the most common mistakes when buying a power rack is measuring only the rack itself.
Before ordering, check:
-
Floor space: Measure the rack's full footprint.
- Ceiling height: Allow for the rack's height and any overhead exercises you intend to perform.
- Barbell clearance: Leave enough room to load plates and move around the bar.
- Bench clearance: Check that your bench can be positioned correctly inside or alongside the rack.
- Access: Make sure the equipment can be delivered into the room and assembled in the intended location.
For a garage gym, also consider where your car, storage and other equipment will sit.
If you're planning a smaller home gym, a half rack or a more compact configuration may be worth comparing with a full power rack.

6. Check Attachment Compatibility
A rack that supports compatible attachments can give you more options as your training changes.
Depending on the system, attachments may include dip bars, landmine attachments, storage trays and cable equipment.
However, compatibility matters. Attachments from different brands may use different upright dimensions, hole diameters and spacing.
Before buying an attachment, confirm that it is compatible with your exact rack model.
The ONYX Power Rack range includes modular configurations and optional additions. Available options vary by configuration, so check the product listing to see what's included and what costs extra.
If you think you'll want more training options later, choosing a rack with a suitable expansion system may help you avoid replacing the entire setup.
7. Decide Whether You Need a Basic Rack or a Complete System
A basic power rack may be sufficient if you mainly want to perform barbell exercises. You'll still need to consider the cost of a barbell, weight plates, and a bench if you don't already own them.
A more comprehensive system may suit someone who wants to combine several training functions.
| Power Rack Setup | Best Suited To | What to Consider |
|---|---|---|
| Basic Power Rack | Barbell focused strength training | Bench, barbell, weight plates and safety components |
| Half Rack | Smaller home gyms | Footprint, stability and safety provisions |
| Rack with Cable System | Strength training with cable exercises | Pulley configuration, resistance and clearance |
| Rack with Smith Machine | People wanting guided barbell movements alongside other exercises | Included features, footprint and total cost |
| Combined Rack Package | People building a more complete gym | Exact inclusions, compatibility and delivery costs |
Compare the complete setup rather than the rack's advertised price alone.
8. Set a Budget Before You Buy
The cost of a power rack varies according to its construction, configuration and included equipment.
A basic rack may be a sensible starting point if you already own weights and a bench. A rack with integrated cable equipment or a Smith machine will generally require a larger budget.
Remember to allow for any additional purchases, such as:
- Barbell and weight plates
- Adjustable bench
- Compatible attachments
- Weight storage
- Suitable flooring
- Delivery and assembly, where applicable
Compare the full cost of the home setup you need. A lower-priced rack may not represent better value if you have to purchase several additional components to make it suitable for your training.
If you prefer to plan a more complete setup, explore the ONYX Home Gym Building Package and check the current equipment options and inclusions.
Frequently Asked Questions
Is a power rack worth it for a home gym?
A power rack can be a worthwhile investment if you regularly perform barbell exercises and have enough room to use it safely. If your workouts mainly involve dumbbells or cable exercises, a different setup may suit you better.
What is the difference between a power rack and a squat rack?
The terms can vary between manufacturers. Generally, a full power rack has four uprights surrounding the lifting area, while a squat rack may use a more open two-post or half-rack design. Compare the actual construction and safety features rather than relying on the product name alone.
Can I add attachments to a power rack later?
Some racks support compatible attachments, allowing you to expand your setup over time. Check the upright dimensions, hole diameter, spacing and manufacturer compatibility requirements before purchasing additional components.
How much space do I need for a home gym power rack?
The amount of space depends on the rack's dimensions and the exercises you plan to perform. Measure the footprint, ceiling height and clearance needed for the barbell, bench and movement around the rack. Follow the manufacturer's recommendations for installation and use.
Should I buy a power rack package or individual equipment?
A package may be convenient if it includes the components you need. Buying individually may make more sense if you already own some equipment or want a specific configuration. Compare the included products, compatibility and total delivered cost.
