Abdominal Crunch & Lower Back | Selectorized dual machine - Pro Tech Series

Dual Selectorized Abdominal Crunch and Back Extension Machine – Pro Tech Series

The dual selectorized Abdominal Crunch and Back Extension Pro Tech Series machine combines two fundamental core exercises in a single piece of equipment, ideal for maximizing performance in optimized spaces without compromising professional quality.

The 1:1 ratio selectorized resistance system provides direct, progressive resistance throughout the entire range of motion. The Q235 steel frame ensures maximum rigidity and stability, while the chrome-plated solid shaft guides and nylon pulley system provide precise, low-friction movement throughout every session.

One roller, two core exercises

The adjustable roller is positioned in front of the torso to perform the abdominal crunch or behind it to train the lower back and glutes, without the need to switch equipment. The dual foot support platform provides stability during both exercises.

Features

• Dual function in one machine: abdominal crunch and lower back extension combined in the same machine.
• Front or rear roller position: switch between both exercises without changing equipment.
• Dual foot support platform: greater stability during exercise.
• Side handles: greater comfort and stability during exercise.
• 1:1 resistance ratio: real, progressive resistance throughout the entire range of motion.
• Precision incremental weight: 2 magnetic 2.3 kg pins included as standard, allowing finer load adjustment than the industry standard.
• Q235 steel frame: anti-corrosion electrostatic coating and maximum rigidity in every component.
• 3 mm reinforced load arm: greater thickness than the industry standard for maximum resistance at the load transmission point.
• Chrome-plated solid shaft guides: high wear resistance and precise movement.
• Nylon pulleys: smooth, quiet, low-friction movement.
• Rubber-coated steel cable: smooth, durable, quiet transmission.
• Carbon fiber upholstery: superior support and comfort under high-intensity loads.
• Magnetic weight selector: magnetic pin for selecting the weight stack, faster, more convenient, and safer than the traditional mechanical pin system.
• bottle and phone holder: integrated into the housing, keeping essentials within reach during training.
