What Does the S901 Do? — 4 Machines in 1 Unit
The S901 combines four distinct lower body exercises into a single space-efficient machine, making it the most versatile leg training solution for Australian commercial and home gym environments:
Exercise 1
45-Degree Leg Press
The angled sled reduces spinal compression compared to vertical pressing, allowing heavier loads with improved safety. Targets quads, glutes, and hamstrings through a full range of motion.
Exercise 2
Hack Squat
Load the sled in reverse for a hack squat position — providing a quad-dominant squat pattern with back support. Ideal for athletes who want depth and tension without axial spinal loading.
Exercise 3
Forward-Facing Squat
A unique third configuration that mimics a barbell squat pattern with the stability and safety of a guided machine. Excellent for lower body hypertrophy and rehabilitation training.
Exercise 4
Calf Raises
The multi-position footplate allows stable loaded calf raises — targeting the gastrocnemius and soleus with heavy plate-loaded resistance that cable machines cannot match.

💡 The Space & Cost Savings Are Significant
A standalone commercial leg press costs $2,000–$4,000. A standalone hack squat machine costs another $1,500–$3,000. The S901 replaces both — plus adds forward squat and calf raise capability — in a single footprint of just 1065 mm wide. For PT studios and home gyms where floor space is money, this is the smart commercial decision.
Is the S901 Suitable for a Commercial Gym or PT Studio?
Yes. The S901 is rated for commercial-frequency daily use. Its 500 kg combined load rating and reinforced steel frame meet the demands of high-turnover commercial environments including PT studios, school gyms, corporate wellness centres, and full commercial fitness facilities. The adjustable safety stops allow confident solo client training, and the plate-loaded design means there are no resistance caps limiting elite athletes or powerlifters.
Plate Loaded vs. Pin Loaded Leg Press — Which Is Better?

For athletes focused on maximum strength, powerlifting, or heavy hypertrophy, a plate-loaded machine like the S901 is the professional choice. The unlimited loading potential and free-weight feel cannot be replicated by a pin-loaded stack.
Full Exercise Library — What Can I Train with the S901?
Quad-Dominant Exercises
-
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
Glute & Posterior Chain Exercises
-
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
Calf & Lower Leg Exercises
-
Standing Calf Raises — use the footplate in calf raise position for heavy loaded gastrocnemius training

Build Quality — What Makes the S901 Commercial Grade?
Reinforced Steel Frame & Load Path Engineering
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.
45-Degree Angle — Why It Matters for Safety & Performance
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.
Adjustable Safety Stops — Training Solo with Confidence
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.

Frequently Asked Questions
Is the S901 suitable for commercial gyms in Australia?
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.
Is plate loaded better than pin loaded for a leg press?
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.
What weight plates does the S901 use?
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.
Does the S901 support calf raises?
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.
How much space does the S901 require?
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.
Can the S901 be used in Australian home gym conditions?
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.
Do you deliver the S901 to Melbourne, Brisbane, and Adelaide?
Yes. Fast tracked freight delivery is available to all Australian capital cities and regional areas including Sydney, Melbourne, Brisbane, Adelaide, Canberra, and beyond. Depot pick-up can also be arranged. Contact us for a freight quote to your specific location.
