Selectorized machenes back extension

The FitGenix Selectorized Back Extension Machine is a guided strength-training device designed to target the erector spinae , glutes , and hamstrings . This machine allows users to safely perform back extensions with adjustable resistance via a weight stack, making it suitable for users of all fitness levels.

The movement involves hinging at the hips while keeping the spine neutral, then extending the torso upward by engaging the posterior chain muscles. The machine features adjustable thigh pads and foot rollers to stabilize the body during motion and ensure proper form, minimizing strain on the lower back.

This exercise helps improve postural stability , core strength , and spinal mobility , and is commonly used in both general fitness and rehabilitative settings to support a healthy lower back.
