Excellent quality and impeccable customer service. I’ve already purchased two kettlebells, one 24 kg and another 32 kg, and now I’m going for the 36 kg one.

IRONSIDE Elite Dual Leg Curl & Extension
The IRONSIDE Elite Dual Leg Curl & Extension is a selectorized dual-function machine designed to combine seated leg extension and seated leg curl into one efficient station. With a 220 lb (100 kg) weight stack expandable to 275 lb (125 kg), it allows complete lower-body isolation work without switching machines—reducing downtime and improving training flow in high-traffic gym environments.
With dimensions of 52 × 43 × 62 in (132.5 × 109 × 157.5 cm) and a total machine weight of 560 lb (254 kg), the unit delivers a solid, stable feel from the first repetition. The resistance comes directly from the stack, not from frame instability, making it ideal for strict sets, high time-under-tension work and progressive overload programming.
Dual Design for Quadriceps and Hamstrings
The core advantage of this machine lies in its dual-exercise architecture, allowing seamless transitions between leg extensions and seated leg curls. This continuity maintains consistent body positioning and reduces setup time, improving efficiency and enabling more precise progression tracking.
The 220 lb (100 kg) selectorized stack offers a wide range for technique, hypertrophy and strength work, with the option to increase up to 275 lb (125 kg) for advanced users.
By combining knee extension and flexion in one frame, the machine supports balanced lower-body development. Alternating between quadriceps-focused extensions and controlled eccentric hamstring curls creates a highly effective training contrast.
Multi-Point Ergonomic Adjustments
The adjustable backrest, thigh pad and ankle roller allow precise alignment of the knee joint for users of different sizes. This ensures that the mechanical axis of the machine matches the anatomical joint axis, reducing joint stress and improving movement efficiency.
The compact seat design is easy to clean and built for high-rotation environments. Combined with dense foam padding and durable upholstery, it provides firm support without compression, maintaining posture and maximizing force transfer to the weight stack.
Controlled Movement and Consistent Tension
The machine is engineered to deliver smooth, consistent resistance across the entire range of motion. This allows for controlled eccentrics, paused repetitions and partials without disruption, supporting precise programming methods such as RIR or RPE-based training.
In leg curls, the adjustable ankle roller ensures optimal leverage without excessive pressure on the Achilles tendon. In leg extensions, the tibial positioning relative to the roller allows fine control over the resistance curve.
This level of precision ensures that performance improvements reflect actual strength gains, not inconsistencies in equipment behavior.
Commercial Use and Programming Efficiency
The footprint of 52 × 43 × 62 in (132.5 × 109 × 157.5 cm) allows it to fit efficiently in compact training spaces without sacrificing adjustability. Its 560 lb (254 kg) frame ensures maximum stability, even under heavy loads.
The expandable weight stack accommodates a wide range of users, from rehabilitation to advanced strength training, eliminating the need for multiple machines.
For gym owners, the quick transitions, intuitive adjustments and easy maintenance make it ideal for high-volume use. For users, it offers consistent mechanics and reliable progression—whether training for hypertrophy, strength or functional performance.

Good product
It’s a very user-friendly and easy-to-use piece of equipment. The members are very satisfied with its benefits.
Very good machine. The only thing I wasn’t completely impressed with was the display, but for the price, the treadmill is perfect for all types of running workouts.
The treadmill is good quality, I recommend it, and I got it at a great price. The only downside is that it took almost a month to arrive. I suggest improving the logistics and shipping process, especially since this is the third time I’ve purchased a product from you.
Excellent purchase!! It’s a high-quality product at a great price. I highly recommend it 100%.
fast delivery, good communication with the customer team
