We've reviewed functional trainers on the market across every budget and fitness goal to bring you the most comprehensive buyer's guide available.

What Is a Functional Trainer?

A functional trainer is a cable based gym equipment machine featuring one or two independent weight stacks connected to adjustable cable pulleys. The cables can be positioned at virtually any height — allowing for an almost unlimited range of functional training exercise angles and movement patterns.

Home gym functional trainers are used for:

• Cable flys and chest press variations
• Lat pulldowns and seated rows
• Shoulder raises and face pulls
• Tricep pushdowns and bicep curls
• Core rotations and woodchops
• Squats and lunges with cable resistance
• Rehabilitation and corrective exercises
• Athletic conditioning and functional training movements

The key advantage of a functional trainer cable machine over free weights is the ability to maintain constant tension throughout the full range of motion. Functional trainer uses range from rehabilitation to elite athletic performance — making it the most versatile piece of gym equipment available for any home gym or commercial gym.

Functional Trainer vs Cable Crossover — What's The Difference?

These terms are often used interchangeably but there are subtle differences worth understanding as a home gym owner:

Functional Trainer: Typically features two independent adjustable cable columns. Most home gym functional trainers include dual weight stacks for independent arm training. The ratio on a functional trainer pulley system — 1:1 or 2:1 — significantly affects the feel of resistance and is an important consideration when buying a functional trainer.

Cable Crossover: Generally refers to a wider stance cable machine specifically designed for cable crossover chest exercises with fixed or limited height adjustment.

The bottom line: A quality all-in-one functional trainer does everything a cable crossover does and significantly more — making it the superior gym equipment choice for any home gym setup where one machine needs to do it all.

Benefits of Functional Trainers

The benefits of functional trainers are extensive for both home gym owners and commercial gym operators:

• Constant cable tension throughout the full range of motion
• Hundreds of functional training exercise variations from a single machine
• Isolateral training capability with dual weight stacks
• Space efficient — replaces multiple single purpose gym equipment pieces
• Suitable for fitness goals ranging from rehabilitation to elite strength training
• Standalone functional trainer designs fit most home gym spaces
• Compatible with a wide variety of functional trainers accessories

Understanding the benefits of functional trainers makes it clear why this is consistently the most recommended piece of gym equipment for serious home gym owners.

What To Look For When Buying a Functional Trainer

Weight Stack on a Functional Trainer

The weight stack functional trainer capacity determines how much resistance you can apply. For most home gym owners a 200-250lb weight stack per side covers every functional training exercise. The weight stack functional trainer spec is the single most important number to check.

Adjustment Positions

More positions means more functional training exercise variety. Look for 19-35 positions for a full-size functional trainer. The ratio on a functional trainer pulley — 1:1 or 2:1 — also affects resistance feel significantly.

Frame Construction

High-quality functional trainers use 11-gauge steel minimum. Commercial functional trainer models use oversized bolts and precision welded frames that handle heavy daily use in any commercial gym or dedicated home gym.

Functional Trainer Features

Functional trainer features worth looking for include:

• Aluminium pulleys for smooth functional training
• Military spec cables for longevity
• Laser cut numbered adjustment positions
• Integrated pull up bar
• Functional trainer and half rack combinations for free weight training
• All-in-one functional trainer designs with smith machine integration
