Hex Press on the Smith Machine: Technique and Equipment

The hex press is one of the few chest pressing variations a gym operator can add without buying a single extra machine. Performed on a Smith machine, it turns a guided bar you already own into a targeted inner-chest movement that members can load safely and without a spotter. This guide covers what the movement really is, how to coach it, how to programme it, and what the equipment underneath it has to deliver in a commercial setting.

What the hex press actually is

The hex press takes its name from the hexagonal dumbbells originally used for it: the hands are pressed firmly together throughout the set, and it is that inward pressure, not the vertical load alone, that drives the contraction of the inner pectorals. On a Smith machine the same intent is reproduced with a narrow grip, hands close together on the bar, elbows tucked in and constant tension towards the midline. The guided bar path allows the work to be done without a spotter, and the bar height setting defines the usable range of motion before the first repetition.

It is worth being explicit about what the hex press is not. It is not a wide-grip bench press. A grip set well outside shoulder width simply turns the movement back into a standard press and loses the inner-chest emphasis that justifies programming it in the first place.

Why the movement earns its place in a commercial gym

The hex press works the pectorals, the shoulders and the triceps, which makes it a useful addition for members chasing a well-defined chest and stronger arms. Beyond the upper-body muscle work, it also trains shoulder stability and intermuscular coordination. Because the bar is guided, the member does not have to spend attention on balancing a free weight and can concentrate on the movement itself.

For an operator, that translates into three practical advantages: the movement can be taught quickly to intermediate members, it does not tie up a second person as a spotter, and it adds variety to an existing chest station without taking up any additional floor space.

Coaching the movement step by step

1. Set the bar height on the Smith machine before loading, so that the bar stops just above chest level.
2. Lie flat on the bench, feet flat on the floor about shoulder width apart, shoulder blades pulled back and down.
3. Take a narrow overhand grip with the hands close together, and press the hands inwards against the bar for the whole set.
4. Lower the bar slowly towards the chest, keeping the elbows close to the body.
5. Press back up until the arms are almost straight, without locking the elbows out completely.
6. Repeat for the number of repetitions planned.

Variations and progressions

Once the basic hex press is mastered, variations keep the stimulus fresh and prevent a plateau.

• Single-arm work. To bias one side of the chest, take the movement off the guided bar and press a single dumbbell with the same inward pressure. A guided bar loaded on one side only is not a safe way to train unilaterally.
• Incline hex press. Set the adjustable bench between 30 and 45 degrees to shift the emphasis towards the upper chest.
• Variable resistance. Add resistance bands or extra load to raise the intensity once technique is consistent.

Programming the hex press

To get results from the movement, it has to sit correctly in the wider training plan.

• Frequency. Two to three sessions per week, with a rest day between each one so the chest and triceps recover.
• Volume and intensity. Start with sets of 8 to 12 repetitions at a moderate load. Increase the load progressively and reduce the repetitions to shift the work towards strength and power.
• Combinations. Pair the hex press with other upper-body work such as push-ups, the bench press or incline flyes.

Common mistakes and safety points

• Do not lock the elbows out. Keeping a slight bend maintains constant tension on the muscle and protects the joint.
• Do not let the bar drop onto the chest. Control the eccentric phase; a bar that falls the last few centimetres is both an impact risk and wasted muscular tension.
• Do not overload the bar. The load has to allow correct form for every repetition of the set.
• Hold the posture. Neutral back, shoulders back, core braced from the first repetition to the last.
• Breathe with the movement. Inhale as the bar comes down, exhale as it is pressed back up.

The equipment underneath the exercise

A movement that members repeat several times a week only stays safe if the hardware is specified for it. In a club, a hotel gym, a corporate facility or a municipal centre, a Smith machine has to be built for continuous commercial duty and certified to EN ISO 20957-1, class S, the class intended for professional supervised use. Bar travel needs to be smooth over the full stroke, with adjustable catches that can be set to the user rather than to the machine.

The bench matters just as much as the bar. A stable, adjustable bench such as the Bodytone FBC08 olympic bench press gives the flat and inclined positions the exercise needs, and keeps the shoulder girdle supported under load.

Frequently asked questions

Does the hex press replace the bench press?

No. It complements it. The bench press remains the main horizontal pressing movement; the hex press adds inner-chest emphasis and shoulder stability work at a lighter load.

Is it suitable for beginners?

Yes, with a light load. The guided bar path removes the balance demand, which makes it one of the easier pressing patterns to coach to a new member, provided the grip stays narrow and the descent stays controlled.

What does a gym need in order to offer it?

A professional class S Smith machine and a stable adjustable bench. Nothing else is required, which is what makes the movement an efficient addition to an existing chest area.

Should members check with a professional first?

Anyone starting a new training programme, and in particular members returning from a shoulder injury, should have the movement cleared and supervised by a qualified coach or health professional.
