VO3 ONYX Series Smith Hip Thruster

Maximize posterior chain power and glute hypertrophy with the VO3 ONYX Series Smith Hip Thruster (BR7031). Engineered for elite commercial gyms, collegiate strength facilities, and boutique fitness studios, the ONYX Smith Hip Thruster eliminates the awkward setup, balance instability, and spinal compensation associated with traditional barbell hip thrusts. Featuring precision linear motion bearings, a multi-dimensional torso bracing system, and an oversized anti-slip footplate, this plate-loaded powerhouse delivers an ultra-smooth, locked-in movement trajectory matching the exact anatomical curve of the hip joint.

Key Features

• Precision Linear Motion Bearing System: Smooth-gliding linear bearings eliminate friction and lateral play, ensuring consistent resistance and maximum muscle recruitment throughout extension.
• Authentic Hip Biomechanical Curve: Designed to replicate the natural movement path of free-weight hip thrusts while providing structural guidance and absolute lifting security.
• Multi-Dimensional Torso Bracing: Features a 4-position adjustable back pad and 7-position shoulder support pads that anchor the upper body, preventing anterior pelvic tilt and lumbar hyperextension under heavy loads.
• 3-Position Starting Height Adjustment: Accommodates athletes of all heights and femur lengths for effortless entry, optimal starting hip angles, and smooth lock-outs.
• Oversized Precision-Angled Footplate: Textured diamond-tread foot platform provides exceptional grip for varied foot stances (narrow, wide, high, or low) to selectively target gluteus maximus, hamstrings, and hip abductors.
• Ergonomic High-Density Hip Bar Cushion: Contoured, heavy-density molded foam barbell pad disperses heavy plate loading across the hips without pinching or discomfort.
• Commercial Heavy-Gauge Frame: Built with PT 50×100×2.5 mm flat oval steel tubing with electrostatic powder coating to withstand 24/7 high-traffic commercial gym abuse.
• Integrated Olympic Weight Storage: Hard-chrome weight horns allow for rapid plate loading and convenient storage of standard 2" Olympic plates.
