S901 Pro Leg Press & Hack Squat Machine | 4-in-1 Commercial Combo (500kg Rated)

• 45-Degree Leg Press — primary quad mass builder; adjust foot position for emphasis shift
• Hack Squat — deep quad stretch with back support; superior for VMO development
• Forward-Facing Squat — barbell squat pattern with guided safety
• High-Foot Leg Press — shift foot plate high to recruit more glute and hamstring
• Narrow-Stance Leg Press — emphasises outer quad sweep
• Single-Leg Press — unilateral loading for imbalance correction

• Wide-Stance Leg Press — targets glutes and inner thighs (adductors)
• Deep Range Leg Press — full hip flexion recruits maximum glute activation
• Sumo Stance Hack Squat — wide foot placement targets glutes and adductors
• Reverse Hack Squat — face the machine for a Romanian deadlift-style glute and hamstring load

• Standing Calf Raises — use the footplate in calf raise position for heavy loaded gastrocnemius training
• Seated Calf Raises (modified) — reduce range to target the soleus muscle
• Single-Leg Calf Raises — unilateral calf development for symmetry
• Donkey Calf Raises — hack squat position with forward lean for deep stretch

• Partial Range Leg Press — post-injury or post-surgery progressive loading
• Slow Eccentric Leg Press — 3–5 second lowering phase for tendon strengthening
• Isometric Holds — static holds at various angles for joint stability
• Blood Flow Restriction (BFR) Leg Press — light load with BFR cuffs for muscle retention during rehab

The S901 frame is constructed from heavy-gauge reinforced steel tubing, engineered to distribute the 500 kg combined load across the full frame rather than concentrating stress at single weld points. This is the key differentiator between commercial-grade machines and cheaper domestic alternatives — which typically use thin 1.5–2 mm steel and fail under sustained heavy loading. The S901 is built to handle daily use in high-turnover commercial environments for years without frame fatigue.

The 45-degree sled angle is not arbitrary. It is the optimal engineering compromise between spinal loading and quad/glute recruitment. A vertical leg press places excessive compressive force on the lumbar spine. A shallower angle reduces the effective loading on the muscles. At 45 degrees, the S901 allows users to train with maximum safe loads while minimising the risk of lower back injury — making it suitable for both elite athletes and rehabilitation clients.

The S901's adjustable safety stops can be set at any depth along the travel path, preventing the sled from descending beyond a safe range. This allows solo training to absolute failure without a spotter — critical for PT studios where clients train independently and for home gym users who train alone. The racking handles allow the user to safely exit the machine at any point in the movement.

Yes. The S901 is designed specifically as a commercial-grade machine with a 500 kg combined load rating and a reinforced steel frame built for high-frequency daily use. It is suitable for PT studios, school gyms, corporate wellness facilities, and full commercial fitness centres across Australia.

It depends on your training goals. A plate-loaded leg press like the S901 offers unlimited loading potential and a true free-weight feel — ideal for strength training, powerlifting, and heavy hypertrophy. Pin-loaded machines offer faster weight changes, making them better suited for circuit training or high-rep PT sessions. For serious strength athletes, plate loaded is the professional standard.

The S901 uses Olympic 50 mm (2 inch) weight plates — the standard for all commercial gym equipment. Standard 25 mm plates will not fit. If you need plates, we stock a full range of Olympic bumper plates and iron plates available separately.

Yes. The multi-position footplate allows stable positioning specifically for loaded calf raises, targeting both the gastrocnemius (full extension) and soleus (bent knee variation). The plate-loaded resistance provides far heavier calf loading than cable or bodyweight alternatives.

The S901 has an assembled footprint of 2192 mm (L) × 1065 mm (W) with a height of 1892 mm. We recommend at least 600–800 mm of clear space at both ends of the machine for safe entry, exit, and plate loading. Total recommended floor allocation is approximately 3.5 m × 2.5 m.

Yes. The powder-coated steel frame is designed to handle the heat, humidity, and dust conditions common in Australian garage and home gym environments. Regular cleaning and occasional lubrication of the sled runners will maintain performance long-term.
