SFE Selectorized Back & Ab Combo Machine

Balanced Core Training

Develop the abdominals and lower back from one space-efficient, commercial-grade station. The dual-function design supports abdominal crunches and back extensions with adjustable positioning, ergonomic support, and smooth selectorized resistance for a balanced core-training experience.

Dual-Function Performance

The abdominal crunch function trains the anterior core, while the back extension movement works the lower back and supporting posterior core muscles. Together these movements work core strength, stability, trunk control, posture-focused training and athletic performance, all without needing two separate machines.

250 lb Selectorized Resistance

The built-in 250 lb weight stack provides substantial resistance for varied experience levels and training goals. Resistance changes quickly through a selector-pin adjustment, allowing efficient transitions between exercises and users without loading or unloading weight plates.

The direct 1:1 pull ratio delivers resistance directly from the selected stack, creating straightforward, repeatable loading that is easy to understand and track.

Adjustable Range of Motion

Customizable range-of-motion settings allow users to refine the starting position and movement path for abdominal crunches and back extensions. This adjustment accommodates different body types, mobility levels, training preferences, and exercise programs.

Smooth Operation and Ergonomic Support

The resistance system delivers fluid, consistent movement for controlled repetitions, technique-focused exercise, strength development, muscle-building programs, and athletic training. Comfortable ergonomic padding provides support and stability during trunk flexion and extension, including higher-resistance sets and repeated use.

Commercial-Grade Construction

A durable commercial-grade steel frame provides the stability and long-term performance required for frequent training. The machine is suited to commercial gyms, fitness centers, strength and conditioning facilities, athletic performance environments, personal training studios, corporate fitness spaces, luxury home gyms, and dedicated core-training areas.
