BB-15 Selectorized Back Extension Glute Trainer

1. Core Functionality
The BB-15 is a selectable strength training device that integrates lower back strengthening, hip shaping, and posterior chain activation. Unlike traditional bodyweight back extension machines, it uses a weighted, selectable resistance system, making the training load more controllable and progressive, suitable for various stages from basic rehabilitation to advanced strength training.

2. Product Specifications
Product Dimensions: 1236 × 990 × 1578 mm
Product Weight: 186 kg
Resistance System: Selectable Weights
Training Mode: Back Extension / Posterior Gluteal Chain Strengthening

3. Training Value
BB-15 focuses on strengthening the body's "posterior kinetic chain," activating the erector spinae, gluteus maximus, and biceps femoris muscles through standardized back extension movements. Long-term training can effectively improve postural problems such as rounded shoulders, hunchback, and anterior pelvic tilt, while also enhancing lower back stability and athletic performance. It is especially suitable for individuals combining strength training and rehabilitation training.

4. Product Highlights
(1) Adjustable Weight System, More Suitable for Progressive Training
Adopting a selective weight structure, the training load can be quickly adjusted to meet the training needs of different stages, from beginner to advanced. Both are suitable for use.

(2) Dual reinforcement design for hips and lower back: Optimized hip support angle allows for greater hip involvement during movement, avoiding excessive load on the lower back alone.

(3) Safer and more stable movement trajectory: Fixed support structure guides a standard extension path, effectively reducing movement compensation and training risks.

(4) Ergonomic support system: Multi-point support design conforms to the pelvis and thighs, improving training stability and comfort.

(5) High-strength commercial-grade structure: The entire body is made of thickened steel, suitable for high-frequency use environments, stable and durable, with low maintenance costs.
