Choosing equipment for a home gym can be confusing, especially when two machines appear to offer similar features.
A functional trainer provides adjustable cable resistance for a wide range of exercises. An all-in-one gym machine can combine cable training with other equipment, such as a power rack, Smith machine, and pull-up station.
Both can be useful for home strength training, but they suit different needs, budgets, and spaces.
The main difference is simple: a standalone functional trainer focuses on cable exercises, while an all-in-one machine combines multiple training systems in one setup.
Here's how to compare them and decide which option makes sense for your home gym.
1. What Is a Functional Trainer?
A functional trainer is a cable-based strength machine, usually featuring two adjustable pulleys that allow you to change the height and direction of resistance.
By moving the pulley positions and changing the handles or attachments, you can perform exercises such as:
- Cable chest flyes
- Standing cable rows
- Triceps pushdowns
- Biceps curls
- Face pulls
- Cable lateral raises
- Woodchoppers and rotational exercises
Many functional trainers use built-in weight stacks, while other systems are plate-loaded.
One advantage of a functional trainer is the freedom to perform movements from different angles. You can also adjust the cable positions to suit your height and the exercise.
A standalone unit can be a good choice if you already have a power rack, bench, and free weights but want to add cable training.
Explore the functional trainers to compare available machines and configurations.
2. What Is an All-in-One Gym Machine?
An all-in-one gym machine combines several training functions within a single equipment system.
Depending on the model, it may include:
- A power rack for barbell exercises
- A Smith machine with a guided barbell
- Adjustable cable pulleys
- A pull-up bar
- Weight storage
- Additional attachment points
This combination allows you to perform different types of strength exercises without purchasing a separate machine for every training function.
For example, you could use the rack for squats, the Smith machine for guided pressing movements, and the cable system for rows and accessory exercises.
However, not every all-in-one machine includes all these features. Always check the specifications and included accessories before buying.
ONYX offers combined configurations, including the Power Rack with Smith Machine and Cable System and other rack and cable combinations. Compare the available options to see which functions are included.
3. Functional Trainer vs All-in-One Gym Machine: Key Differences
The following table summarises the main differences.
| Feature | Functional Trainer | All-in-One Gym Machine |
|---|---|---|
| Main Purpose | Cable-based strength training | Multiple types of strength training |
| Cable Exercises | Yes, depending on configuration | Usually included when equipped with a cable system |
| Barbell Training | Requires separate equipment unless integrated | Often available through a rack or Smith machine |
| Squats and Bench Presses | Requires a suitable rack or separate setup | Possible on models with the appropriate rack or Smith system |
| Exercise Variety | Extensive cable exercise options | Cable exercises plus other training systems, depending on the model |
| Space Requirements | Varies by design; standalone units need dedicated space | Can combine multiple functions within one footprint |
| Additional Equipment | May require separate free weights and a bench | Some models combine several systems, but additional equipment may still be needed |
| Best Suited To | People prioritising cable training | People wanting multiple training functions in one system |
The right choice depends on the exercises you perform most often, the equipment you already own and the space available.
4. Which Machine Offers Better Value for Money?
The initial price is only one part of the decision. You should also consider what else you need to buy to complete your home gym.
When a functional trainer offers better value
A standalone functional trainer may be the better option if you already own a power rack, barbell, weight plates, and bench.
In that situation, you may only need to add cable training to your existing setup. Buying another rack or Smith machine could mean paying for equipment you already have.
You should also compare the pulley configuration, resistance system, adjustment positions, and included accessories.
When an all-in-one machine offers better value
An all-in-one system may make more sense if you're building your gym from scratch and want several training functions in one purchase.
Instead of sourcing a rack, cable machine, and other equipment separately, you can compare combined systems designed to work together.
However, check exactly what's included. Some systems require separate purchases for benches, barbells, plates, or attachments.

5. Which Machine Is Better for a Small Home Gym?
Available space can be a deciding factor, but don't assume that every all-in-one machine takes up less room than every functional trainer.
A standalone functional trainer needs enough clearance for cable exercises, while a combined system may have a larger frame but replace several separate machines.
Before buying, check:
- Overall width, depth, and height
- Ceiling clearance
- Space needed to move around the machine
- Room for a bench and other accessories
- Access for delivery and assembly
Also consider how the equipment will fit into your normal routine. A machine that offers many functions isn't necessarily the best choice if it leaves too little room to perform exercises comfortably.

6. What About a Functional Trainer With a Power Rack?
There is another option worth considering: a combined functional trainer and power rack.
This type of setup sits between a standalone cable machine and a more comprehensive all-in-one system.
Depending on the model, it can provide adjustable cable exercises alongside traditional barbell training without necessarily including a Smith machine.
It may suit someone who wants to perform squats, bench presses, pull-ups, and cable exercises in one training area.
For example, ONYX offers a Functional Trainer Power Rack with Cable.
Compare the rack dimensions, cable arrangement, safety components, and available attachments before deciding whether this configuration meets your needs.
7. Which One Should You Choose?
Use your training priorities to narrow down the options.
Choose a functional trainer if:
- You mainly want cable-based exercises.
- You already own a power rack and free weights.
- You want adjustable pulley positions for different movements.
- You don't need another barbell or Smith machine setup.
Choose an all-in-one gym machine if:
- You're building a home gym from scratch.
- You want cable training alongside rack or Smith machine exercises.
- You prefer to consolidate multiple training functions.
- You have enough space and budget for a combined system.
Consider a functional trainer with a power rack if:
- You want both cable and barbell training.
- You don't necessarily need a Smith machine.
- You want to compare a more focused combination against a fully equipped system.
There is no single best option for everyone. The most suitable machine is the one that provides the training functions you will actually use and fits your space and budget.
Frequently Asked Questions
Is a functional trainer enough for a home gym?
It can be enough for someone whose training centres on cable exercises. However, if you also want to perform heavy barbell squats and bench presses, you'll need suitable additional equipment or a combined system that supports those exercises.
Is an all-in-one gym machine worth buying?
It can be worthwhile if you want multiple training functions in one setup. Compare the included features, dimensions, and total cost with the price of buying separate equipment.
Can I build muscle with a functional trainer?
Yes. Cable exercises can support muscle-building training when you use appropriate resistance, perform exercises with good technique, and progressively increase the training challenge. Your results will also depend on your overall programme, nutrition, and recovery.
Should I buy a functional trainer or a Smith machine?
They serve different purposes. A functional trainer provides adjustable cable resistance, while a Smith machine uses a guided barbell. If you want both types of training, consider a combined system that includes both.
What should I check before buying an all-in-one gym machine?
Check its dimensions, exercise functions, resistance system, weight capacity, safety features, included attachments, and installation requirements. Also confirm whether you need to purchase a bench, barbell, plates, or other accessories separately.
