Leg Extension & Leg Curl Bench Attachment

REP’s Leg Extension & Leg Curl Bench Attachment turns a compatible REP bench (BlackWing, Nighthawk, or ZeroGap AB-5000/AB-5100) into a dedicated quad-and-hamstring station without the floor space of a standalone machine. It locks in with a wheel-assisted, one-person pop-pin setup and supports three resistance options — weight plates, resistance bands, or (with the optional Cable Kit) a functional trainer or cable stack — usable individually or layered together. A flat thigh pad spreads load evenly across the legs for leg curls instead of using a traditional roller, while adjustable shin pads and side handles support the leg extension.

Independent coverage is mixed. One reviewer ranked it A-tier among bench-attachment leg extension/curl options, calling it better than expected for the price, though he flagged the leg curl as clearly the weaker of the two movements. A more critical review reported units arriving with quality-control issues (bent parts, loose roller end caps) and a “bell curve” resistance profile that’s lightest exactly where lifters want the most tension — concluding it costs more than rivals like the Freak Athlete ABX without matching their resistance feel or feature set. It’s rated for 250 lbs and weighs roughly 90 lbs assembled.
