ISO-Lateral Chest Press DRE8001
ISO-Lateral Chest Press DRE8001
The Dynasty Fitness DRE8001 ISO-Lateral Chest Press is a selectorized chest press machine with independent converging arms that move on separate pressing paths, so each side of the chest works through its own full range of motion and contraction without the stronger arm compensating for the weaker one across any rep. A dual-handle design provides two biomechanically distinct pressing options from the same station: outward-angled horizontal handles that stabilise the shoulder blade and prevent anterior shoulder drift delivering a true 1:1 felt weight ratio per arm, and inward-angled vertical handles that shift the emphasis toward the mid-to-lower pectorals with reduced triceps involvement at an approximately 1:0.86 felt weight ratio, giving each grip a specific muscle targeting function rather than offering the same press at a different wrist angle. An assisted footplate system reduces shoulder stress at the start of each set and provides support at failure so the movement begins and ends safely regardless of load, and a precision pneumatic rack-and-pinion seat adjusts single-handed to the correct press height for any user in seconds. Built to commercial grade at 56"×55"×63" with a 210 lb standard stack and a 250 lb upgrade option available through Dynasty Fitness, the DRE8001 is built for commercial gyms, personal training studios, and serious home gym setups where ISO-lateral pressing with biomechanically specific dual-handle geometry is a chest programming priority.
- ISO-lateral independent converging arms move on separate pressing paths so each side of the chest drives through its own full range of motion and peak contraction without the stronger arm taking over, producing a more balanced chest stimulus than fixed bilateral press machines deliver at the same load
- Dual-handle design with outward-angled horizontal handles at a true 1:1 felt weight ratio per arm for scapula-stabilised pressing, and inward-angled vertical handles at an approximately 1:0.86 felt weight ratio that shift emphasis toward the mid-to-lower pectorals with reduced triceps involvement, giving each grip a distinct biomechanical purpose on the same machine
- Assisted footplate system reduces shoulder stress at the start of every set and provides a controlled support point at muscle failure, so the initiation and the finish of each heavy pressing set are mechanically safe without a spotter
- Precision pneumatic rack-and-pinion seat adjusts single-handed to the correct press height instantly, keeping session flow uninterrupted between sets and between users without the resistance or imprecision of manual seat pin systems

Exercises and muscles targeted
Exercises and muscles targeted
| Exercise | Muscles Targeted |
|---|---|
| ISO-Lateral Chest Press — Horizontal Handle | Pectoralis Major — Sternal Head (primary — outward-angled handle stabilises scapula, full horizontal press path), Pectoralis Major — Clavicular Head (secondary), Anterior Deltoid (secondary), Triceps Brachii (secondary), Serratus Anterior (scapular stabiliser) |
| ISO-Lateral Chest Press — Vertical Handle | Pectoralis Major — Sternal and Lower Head (primary — inward-angled vertical handle shifts emphasis toward mid-to-lower chest), Anterior Deltoid (secondary), Triceps Brachii (reduced compared to horizontal handle — inward angle reduces triceps involvement), Serratus Anterior (stabiliser) |
| Unilateral ISO Press (single arm) | Pectoralis Major (unilateral — one side driving independently, primary), Core (anti-rotation stabiliser under asymmetric load), Anterior Deltoid (secondary), Serratus Anterior (increased unilateral scapular stabilisation demand) |
| ISO Press — Isometric Hold (peak) | Pectoralis Major (sustained isometric at full arm extension — peak contraction), Anterior Deltoid (co-contraction), Triceps Brachii (isometric at lockout), Serratus Anterior (sustained stabiliser) |
| ISO Press — Slow Eccentric | Pectoralis Major (eccentric stretch loading from peak extension through to the deepest starting position — maximum hypertrophy stimulus), Anterior Deltoid (eccentric), Triceps (eccentric), independent arm paths allow each side to lower at its own natural arc without interference |
| Alternating ISO Press | Pectoralis Major (alternating unilateral press per rep — each side drives independently through full convergence path), Core (rotational stabiliser demand per alternating rep), Anterior Deltoid (secondary per press) |
The ISO-lateral chest press trains both sides of the pectoralis major through independent pressing arcs that converge toward the centre at the end of each rep, replicating the natural inward adduction motion of the pectoral muscle more closely than a fixed bilateral bar press. The horizontal handle delivers a 1:1 felt weight ratio per arm for a direct, measurable pressing stimulus with scapular stability. The vertical handle at approximately 1:0.86 felt weight ratio shifts the emphasis toward the mid-to-lower chest by changing the wrist and elbow angle, reducing triceps co-activation so the pectoral carries more of the pressing load. The assisted footplate allows the user to initiate every set without the shoulder instability that starting a heavy press from a fully loaded position can create.
