ADD-ON

The REP® Nighthawk™ adjustable weight bench is a high-performance bench engineered for strength that builds on the success of the popular AB-4100. It features strategic upgrades that enhance stability, versatility, and lifter experience. While many adjustable benches prioritize size and weight capacity at the expense of maneuverability and practicality for small spaces, this compact weight bench does it all — delivering top-tier build quality and functionality. Ideal for home gyms or commercial fitness spaces aiming to maximize space, the Nighthawk™ adjustable bench wider rear foot and full-contact front foot offer unmatched stability during workouts, all without increasing the bench's weight. This bench is intended for home gym and light-commercial use, such as boutique fitness and personal training studios.
The closed ladder-style adjustment system features thick, robust ladders with smooth and satisfying adjustments. The molded polyurethane pad, wrapped in REP's signature CleanGrip™ vinyl, offers excellent grip, support, comfort, and durability. This bench also is compatible with attachments, such as the Adjustable Bench Leg Roller, with additional attachments in development, including a leg curl/leg extension attachment, for enhanced workout versatility. The REP® Nighthawk™ adjustable bench features a durable yet lightweight build and tactical weight distribution, making its 88lbs feel as light as, if not lighter than, the AB-4100, ensuring effortless mobility. Featuring a knurled front handle and heavy-duty wheels, this adjustable bench is an essential addition to any gym.
Other highlights include:
- •Versatile Adjustments: It has seven back positions (0, 15, 30, 45, 60, 75, 85 degrees) and four seat positions (-15, 0, 10, 20 degrees) for versatile training.
- •Durability: Constructed from 7- and 14-gauge steel, the frame is engineered to deliver exceptional durability and stability while maintaining a lightweight and compact design. Its tripod design, featuring a wide rear base and sturdy front foot with a full-contact liner, ensures rock-solid stability on any floor surface.
- •IPF Compliant: With a 16.7” height, this bench complies with International Powerlifting Federation standards, so you can train how you'll be lifting in competitions. This height also allows for a flat-foot leg drive for shorter lifters.
- •Vertical Storage: A built-in upright storage post with rubber coating protects the pads and ensures stability when stored vertically — saving space.
- •Sleek Design: Knurled handles, black nickel finish, low-profile hardware, and wheel covers elevate both aesthetics and usability.
- •Color Options: The bench is available in multiple colors, each paired with metallic black ladders for a modern, cohesive look. The matte black option features a matching matte black ladder for a sleek, uniform aesthetic.

The REP® Nighthawk™ adjustable bench builds on the success of the AB-4100 with newly added features and improved functionality. Updated aesthetics and improved details make it look sleeker and feel easier to move. A redesigned molded pad improves both comfort and durability. Stability is improved with newly optimized front and rear feet and improved molded plastics.
The wider rear foot allows REP® Ares™ attachment 2.0 users to position the bench deeper into the rack. This enables a better incline and flat bench press experience.
A closed ladder design prevents you from lifting the back post out of the ladder when adjusting your bench. When storing or moving the bench vertically, it keeps the back pad from swinging around. Learn more about ladder-style adjustable benches here.
No, the ladders will be metallic black on all benches except the matte black option. Those will come with matte black ladders.
No, but the REP® Nighthawk™ bench has a wide back pad option – coming soon!
Keep all bolts loose until the bench is fully assembled; then tighten all bolts to complete your assembly.
