The ISO-lateral flat bench press is the machine-format equivalent of the barbell flat bench press, performed from the same supine lying position with the scapulae retracted against a flat bench surface. The independent bilateral arm design separates what a shared barbell combines into a single bilateral movement, allowing each pectoral to be loaded and taken to failure independently within a single set. This means left-right pectoral strength differences that a barbell accommodates by tilting and shifting are fully isolated on the DSH045, making it the ideal complement to barbell bench pressing for athletes who want both compound and ISO-lateral pressing in their chest programme.

Who this machine is built for

Serious Home Gym Builders
The DSH045 at 67.4" × 75.0" × 37.8" is a flat-profile machine that fits under standard ceiling heights and occupies comparable floor space to a commercial flat bench with a barbell setup, at 238 lbs net weight before plates and with both plate storage horns on the machine. For a home gym where the flat bench press is the primary chest exercise, the DSH045 delivers the same pressing position with ISO-lateral arm independence and guided path consistency that a barbell cannot provide.

Bodybuilders and Physique Athletes
The barbell flat bench press trains both pectorals simultaneously through a shared bar that compensates for any imbalance between sides. The DSH045 ISO-lateral design forces each pectoral to complete its full press independently, making the weaker side's deficit immediately apparent and requiring it to work through the full range without the stronger side carrying it. Running ISO-lateral sets alongside barbell bench work covers both the bilateral strength adaptation and the bilateral symmetry correction that complete pectoral development requires.

Powerlifters and Strength Athletes
The flat bench press is the primary competition lift for the upper body in powerlifting, and the ISO-lateral machine version provides supplementary pressing volume that builds pectoral and anterior deltoid strength at the bench press angle without the bar path management and spotting requirements of the barbell. The guided arc also allows maximum-effort eccentric loading at heavy bilateral weights without the unrack and rack demands of a barbell setup, which makes it practical for high-volume pressing accessory work after competition lift training.

Commercial Gym Owners and Operators
A plate-loaded ISO-lateral flat bench press serves members who have reached the strength levels where barbell flat bench pressing is their primary heavy compound upper body exercise and want a machine alternative at equivalent load that addresses bilateral compensation. The low 37.8" profile makes it one of the most visually open machines in the DSH series, fitting naturally in a commercial chest training area without blocking sight lines.

Private Personal Training Studios
The guided arm path removes bar path management from the trainer's coaching focus, allowing full attention to scapular position, elbow angle, and pectoral engagement cues during the pressing set. The independent arms make bilateral strength differences immediately visible and trackable across sessions without any assessment equipment, which supports targeted programming for clients with observable left-right pressing asymmetries.

How to setup and use

Setting Up the DSH045 ISO-Lateral Bench Press

Load Olympic plates evenly onto the bilateral weight horns, keeping amounts equal on each side within the 661 lb capacity. The machine has two standard and two long plate storage horns keeping additional plates organised on the frame during the session.
Lie on the back pad in the supine position with the back flat against the bench, feet planted on the floor at a comfortable stance that allows the lower back to stay in contact with the pad.
Retract and depress the shoulder blades actively against the bench pad before gripping the handles. This scapular retraction position is the foundation of the press and should be established and held before any movement begins.
Grip both oversized rubber-coated handles at the natural hand position where the wrists feel neutral — not bent backward or rotating inward under the press load.
Confirm both shoulder blades are in firm contact with the bench pad and both feet are planted before beginning the first rep.
Load with Dynasty Fitness Urethane Grip Plates for a clean bilateral setup across all weight horns.

Performing the Exercise

From the starting position with both arms lowered and the pectorals in a full stretch, press both arms upward and slightly together through the biomechanically aligned arc until reaching full arm extension.
Keep both shoulder blades pressed into the bench pad throughout the press — if the shoulders rise off the pad as the arms extend, reduce the load until the scapular position can be maintained through the full range.
Hold the extended position for one second at peak pectoral contraction before beginning the return.
Lower both arms back to the starting position under control over at least two seconds, allowing the full pectoral stretch to develop at the bottom before each rep.
For unilateral sets, keep one arm in the starting position and press only the working arm through the full arc, engaging the core against the rotational demand.
After the final rep, return both arms to the starting bottom position before releasing the handles and sitting up.

The Dynasty Fitness DSH045 ISO-Lateral Bench Press is a plate-loaded bilateral chest press machine where the user lies flat on the ergonomically contoured bench pad in the same supine position as a barbell flat bench press, pressing independent left and right arm frames upward through a biomechanically aligned arc that matches the natural pectoralis major fibre direction and shoulder joint trajectory. Independent arm frames on four 6206-2Z bearings mean each pectoral works completely separately against its own bilateral plate load, eliminating the stronger side from compensating for the weaker through a shared barbell, and the lying position with full back supported against the bench pad replicates the scapular anchoring and force production environment of the barbell bench press in a guided machine format that removes bar path instability. Oversized rubber-coated handles accommodate the natural hand positioning of the flat bench press grip without forcing the wrists into stress. Built from PT60×120×2.5mm steel with a 661 lb bilateral load capacity in matte black at 67.4" × 75.0" × 37.8", the DSH045 is built for commercial gyms, personal training studios, and serious home gym setups where the flat bench press movement is a primary chest training tool.

Plate-loaded ISO-lateral flat bench press where the user lies supine on the bench pad and presses upward through a biomechanically aligned arc, replicating the barbell bench press movement in a guided machine format at up to 661 lbs bilateral
Independent left and right arm frames on four 6206-2Z bearings train each pectoral separately so the dominant side cannot assist the weaker through a shared bar, revealing and correcting bilateral chest strength asymmetries across every set
Oversized rubber-coated handles accommodate the natural hand spacing and wrist alignment of the flat bench press grip, reducing wrist stress under heavy horizontal pressing loads that narrow handles concentrate at specific contact points
Full back contact with the ergonomically contoured bench pad supports the scapulae in the retracted pressing position so the pectoral carries the full bilateral load without the shoulder rising off the bench and converting the press into an anterior deltoid exercise

Key Features

ISO-Lateral Independent Arm Frames

Left and right arm frames pivot on four 6206-2Z bearings across two shaft φ30×112×M12 pivot axles, each arm working completely independently from the other through the press arc. The pectoral on each side must complete the full press movement against its own bilateral plate resistance without assistance or masking from the opposite arm. Safety bushing assemblies x2 and safety covers x2 limit each arm's travel, and snap springs x2 prevent uncontrolled arm drop at the end of a set.

Biomechanically Aligned Press Arc

The arm frames are engineered to follow the natural pectoralis major fibre direction and the shoulder joint's movement trajectory through a horizontal pressing motion from the supine lying position. The arc replicates the press path of a correctly executed flat barbell bench press without the lateral bar sway and bilateral load compensation that a shared barbell introduces. The guided path stays consistent through every rep regardless of fatigue or bilateral load imbalance between the two plate horns.

Ergonomically Contoured Bench Pad

The back pad is shaped to support the full thoracic spine and upper back in the supine pressing position, with contours that distribute the back contact load across the full surface rather than creating pressure points at the lumbar or mid-thoracic region. The bench pad width and surface provide stable bilateral shoulder blade contact that keeps both scapulae in the retracted, depressed position through the pressing arc. Snap springs prevent the arm from falling unexpectedly when repositioning between sets.

Oversized Rubber-Coated Handles

The large-diameter rubber-coated handles fit the natural hand and finger geometry of the flat bench press grip, where the handle diameter is wide enough to allow the thumb to wrap around the full circumference without the wrist bending backward under the pressing load. The rubber surface maintains a secure non-slip grip through the press arc from the starting lowered position through to full extension. Grips are positioned at the natural hand-to-shoulder width spacing that the flat bench press uses.

Low-Profile Frame with Four Plate Storage Horns

The PT60×120×2.5mm steel frame sits at 37.8" height approximately waist height for most users making the DSH045 one of the lowest-profile machines in the DSH plate-loaded series. Two standard weight plate storage horns and two long weight plate storage horns keep the full range of loading denominations available directly on the machine frame across a commercial session without requiring a separate plate tree nearby. Two adjustable levelling feet ensure the bench sits flat on any floor surface.

Q: How is the ISO-Lateral Bench Press different from the Chest Press DSH001?
A: The DSH045 is a lying bench press machine — the user lies flat on the bench pad in the same supine position as a barbell flat bench press and presses upward. The DSH001 is a seated chest press machine where the user sits upright and presses forward. Beyond the body position difference, the bench press position allows greater pectoral stretch at the bottom of the press and a more direct carry-over to barbell bench press mechanics. Both target the mid-sternal pectoralis major but through fundamentally different body orientations.

Q: Why is the ISO-lateral design better than a standard shared-bar bench press machine?
A: A shared-bar bench press machine links both arms through the same bar or mechanism. The stronger pectoral can contribute more force to the shared movement without the weaker side keeping up, and this compensation is invisible during the set. The ISO-lateral independent arms on the DSH045 give each pectoral its own resistance to overcome completely. If the left pectoral is weaker than the right, the left arm will complete fewer reps or complete them more slowly at the same load, making the asymmetry immediately visible and programmable.

Q: Should I retract my shoulder blades on this machine the same way as on a barbell bench?
A: Yes. Scapular retraction and depression are the foundation of effective flat bench pressing regardless of whether the resistance is a barbell or the DSH045 arm frames. Retract both shoulder blades before gripping the handles, maintain that retraction through the full press, and keep the back flat against the bench pad at peak extension. If the shoulders peel off the pad at the top of the press, the anterior deltoid takes over as the primary driver and the pectoral stimulus is reduced. The contoured bench pad is designed to support the retracted scapular position naturally.

Q: Can I use this machine as my main bench press if I train without a spotter?
A: Yes. The safety bushing assemblies and arm travel limiters on each independent arm define the maximum downward range so the arms stop at the designed bottom position rather than continuing beyond safe chest contact. The snap springs prevent the arms from dropping uncontrolled when releasing the handles. These two safety systems make solo maximum-effort bench press sets practical on the DSH045 without the need for a spotter or a power rack safety system.

Q: What is the difference between using the standard and long weight plate storage horns?
A: The two standard storage horns hold smaller diameter plates such as 10 lb and 25 lb denominations that are used for warm-up and fine loading increments. The two long storage horns accommodate larger diameter 45 lb plates that are too wide for standard-length horns. Having both on the machine keeps the full denomination range immediately available during a pressing session without requiring separate plate tree access between sets.

Q: What Dynasty Fitness machines pair with the DSH045 for a complete chest programme?
A: The DSH045 covers ISO-lateral flat bench pressing from the supine position targeting the mid-sternal pectoral. Pair it with the Chest Press DSH001 for the seated flat press variation, the Incline Press DSH002 for the upper clavicular head through an incline arc, and the Wide Chest Press DSH012 for the lower sternal fibres through the wide press angle. The Chest Fly DSH049 adds pectoral isolation through horizontal adduction that none of the pressing machines replicate with the same pure fly movement pattern. Load the DSH045 with Dynasty Fitness Urethane Grip Plates for a clean, balanced bilateral setup across both working horns.
