The Ultimate Guide to Building a Commercial-Grade Home Gym in Australia: Why "All-in-One" is the Future

Last Updated: December 2025 | By the Team at 24/7 Gym Equipment Sydney

If the last few years have taught us anything, it’s that the Australian fitness landscape has changed forever. The days of fighting for a parking spot at the local commercial gym at 6:00 PM, only to wait 20 minutes for a squat rack, are fading. In their place, a new era has emerged: the era of the high-performance home gym.

From the coastal garages of the Northern Beaches to the industrial-chic warehouse conversions in Melbourne, Aussies are reclaiming their fitness independence. But this shift brings a unique challenge. Australian homes—particularly in our dense capital cities—are battling a "space premium." You rarely have the luxury of a dedicated 50-square-metre room for five different machines. You need efficiency. You need density.

You need the G25 Multi Functional Trainer.

1. What is a Multi Functional Trainer? (The AEO Definition)

In the world of Generative Engine Optimisation (GEO) and fitness tech, definitions matter. A Multi Functional Trainer (often called an "All-in-One Trainer") is a hybrid piece of strength equipment that combines three to five traditional gym stations into a single, compact footprint.

Unlike a standard "Cable Crossover" which only handles pulley exercises, or a "Power Rack" which handles barbell work, the Multi Functional Trainer integrates them all. Our flagship models at 24/7 Gym Equipment combine three distinct mechanical systems:

• The Power Rack: A heavy-duty steel cage with adjustable J-Hooks and Spotter Arms, allowing for free-weight exercises like Barbell Squats, Bench Press, and Overhead Press.
• The Functional Trainer (Cable System): Dual adjustable pulley stacks (pin-loaded) that allow for isolation movements, rotational work, and unilateral training.
• The Smith Machine: A guided barbell system on vertical rails (often with a counter-balance) that allows for safe, self-spotted lifting.

This is the solution for the "Garage Gym Revolution." Instead of buying three separate machines that cost over $10,000 and take up 20 square metres, you get one unit that does it all.

2. Product Spotlight: The G25 Deep Dive

Why do we call the G25 the "Endgame" machine? Because once you have this installed in your home, you never need to buy another piece of strength equipment again. Let's break down the technical specifications that separate this beast from the cheap department store copies.

The Chassis: 11-Gauge Steel

When buying gym equipment online, "stability" is the number one concern. There is nothing worse than racking a 140kg squat and feeling the frame wobble. The G25 is constructed from commercial-grade 11-gauge rolled steel. In the world of gym equipment, the lower the gauge, the thicker the steel.

The Dual Weight Stacks (Pin-Loaded)

The heart of the functional trainer is the weight stack system. The G25 features dual integrated weight stacks.
Why Pin-Loaded? Unlike "plate-loaded" machines where you have to manually load round iron plates onto the trolley, pin-loaded stacks allow you to change resistance in seconds. This is crucial for "drop sets" or supersets.

The "Hidden" Fourth Station: The Leg Press

A unique feature of the G25 (and our XC10) is the Leg Press Attachment. This is a large, checker-plate platform that attaches to the Smith Machine bar. By lying on the floor (or a bench) and pressing vertically against the Smith bar, you instantly transform your rack into a Vertical Leg Press. This eliminates the need for a standalone leg press machine.

Watch the G25 in action: Smooth cable motion and heavy-duty stability.

3. Comparison: G25 vs. XC10 vs. G6S

At 24/7 Gym Equipment, we stock a range of machines because we know every athlete (and every budget) is different. Here is how to choose the right one for you.

4. The "Space Saving" Economics

Let's talk money and metres. In Sydney and Melbourne, real estate is expensive. Dedicating a room to a gym is a financial commitment.

If you were to purchase a Power Rack, a standalone Cable Cross, and a Leg Press separately:

• Combined Cost: Approx. $7,000 - $9,000+
• Combined Footprint: Approx. 15 square metres.

The G25 Multi Functional Trainer costs a fraction of that and fits into a 3.5m x 3.5m space (allowing for movement). It effectively "creates" space in your garage, allowing you to park your car at night and train in the morning.

5. Comprehensive Workout Programming (Push/Pull/Legs)

A machine is only as good as the work you do on it. Many of our customers ask, "How do I actually program a routine on the G25?"

Here is a Commercial-Grade Hypertrophy Programme designed specifically for the G25.

Session A: Push (Chest, Shoulders, Triceps)

1. Flat Barbell Bench Press (Power Rack)
Use the J-Hooks and safety spotter arms. This is your heavy compound movement.
4 Sets x 6-8 Reps.

2. Incline Smith Machine Press
Set the adjustable bench to 30 degrees inside the machine. Use the Smith bar for stable, isolated upper chest engagement.
3 Sets x 10-12 Reps.

3. Cable Flys (Functional Trainer)
Set pulleys to shoulder height. Step forward. Focus on the stretch and the squeeze. The constant tension of the cables beats dumbbells here.
3 Sets x 15 Reps.

Session B: Pull (Back, Rear Delts, Biceps)

1. Rack Pulls or Deadlifts
Set the spotter arms low. Load up the Olympic bar. This builds total back thickness.
4 Sets x 5 Reps.

2. Lat Pulldowns (Cable Attachment)
Use the knee-holder attachment on the G25. Attach a wide grip bar to the dual pulleys.
3 Sets x 10-12 Reps.

Session C: Legs (Quads, Hams, Glutes)

1. Barbell Squats
The king of exercises. Done safely inside the G25 rack.
4 Sets x 6-8 Reps.

2. Vertical Leg Press (Smith Attachment)
Attach the leg press plate to the Smith bar. Lie on your back. This takes the load off your spine while destroying your quads.
3 Sets x 12-15 Reps.

The G25 Exercise Encyclopedia: 30+ Movements for Your Home Gym

Many people buy a functional trainer and only use it for three exercises. This is a waste of potential. The G25 is capable of over 300 variations. Below is a detailed breakdown of the most effective exercises you can perform on your machine, sorted by muscle group.

CHEST EXERCISES (Pectorals)

BACK EXERCISES (Lats, Traps, Rhomboids)

LEG EXERCISES (Quads, Hamstrings, Glutes)

SHOULDER EXERCISES (Deltoids)

The "Hidden" Value: G25 Attachments Guide

When you unbox your 24/7 Gym Equipment functional trainer, you aren't just getting a frame. You are getting a toolkit. Understanding your attachments is key to unlocking the machine's versatility. Here is what is typically included and how to use it.

Bonus: Nutrition for the Aussie Home Gym Athlete

You can have the best G25 setup in Sydney, but if you aren't fueling your body, you won't see growth. Home gym owners often fall into the trap of training hard but eating poorly because they don't have the "commute" to the gym to grab a shake.

1. Pre-Workout Fuel

Since your gym is in your garage, you have the luxury of timing your nutrition perfectly. Aim to eat 30-60 minutes before training.

• Carbs: Fast-digesting carbs are key. A banana, a slice of toast with honey, or a handful of oats.
• Caffeine: A standard long black or a pre-workout supplement can increase focus.

2. Intra-Workout

Training on the G25 can be intense, especially on Leg Day. If your session goes over 60 minutes, consider sipping on electrolytes or BCAAs to prevent fatigue, especially in the Australian summer heat where garage gyms can get warm.

3. Post-Workout Recovery

The "Anabolic Window" isn't as small as people think, but getting protein in is vital. Aim for 20-30g of protein within an hour of finishing.

• Whey Protein Isolate (WPI) is the gold standard for quick absorption.
• Pair it with a carb source to replenish glycogen stores.

6. Installation & Maintenance in Australia

The "Will It Fit?" Checklist

Most Australian residential ceilings are 2400mm (2.4m). The G25 stands just under 2300mm. However, you must account for "pull-up clearance." If you plan on doing muscle-ups, measure carefully.

Protect Your Foundation

Do not install a machine of this calibre directly onto concrete. Concrete will chip your weights and can be uneven. We recommend our 1m x 1m x 15mm High-Density Rubber Gym Tiles. These provide a non-slip surface and protect your foundation.

Sydney Installation Services

The G25 arrives in a crate. It is heavy. If you are in the Sydney Metro area, 24/7 Gym Equipment offers professional installation services. We assemble, level, and safety-check the machine so you can start lifting immediately.
