Description

TKO Achieve Dual Leg Extension/Curl for Balanced Thigh Training:

The TKO (8806-BK) Leg Extension/Curl Machine combines seated leg extensions and seated leg curls in one selectorized station for quadriceps and hamstring training. An adjustable back pad and multiple exercise starting positions help users establish an effective setup for both movements, while the shared resistance system keeps transitions simple between exercises. The compact dual-function design works well in home gyms, hotels, apartment communities, corporate wellness rooms, community centers, studios, and other light-commercial settings where floor space matters.

Exercise-Specific Adjustments Help Align the User with the Pivot:

This quad extension and curl machine lets users reposition the back support and movement start for the selected exercise, helping accommodate different body sizes and preferred ranges of motion. The seated format keeps both quadriceps and hamstring work at one station, while the selectorized resistance system makes load changes quick between sets. An instructional placard also provides a convenient setup reference for users training without direct coaching.

Enclosed Light-Commercial Design Supports Shared Fitness Rooms:

This TKO Achieve Dual Leg Extension & Curl Machine uses electro-welded steel construction, high-use upholstery, reinforced pulleys, commercial cable, and a fully shrouded resistance system. The black frame and upholstery create a coordinated appearance with other Achieve Dual stations, while an available resistance upgrade accommodates facilities that need greater loading potential. Combining two common lower-body isolation exercises in one machine gives light-commercial facilities useful programming variety without dedicating separate floor space to each movement.

    Great Machine

    Posted by Henry Zhang on Aug 16, 2025

    This is my second purchase from this company, and once again, the delivery was impressively fast, arriving the very next day. A truck with a lift gate dropped the machine directly in my garage, which made things much easier. Assembly itself isn’t overly difficult, but it is tedious and definitely a test of character. I broke it into two sessions, and overall the process took about four hours. You’ll need two different sizes of ratchets and sockets or it will take even longer. One important tip is that this machine weighs around 600 pounds and cannot be moved once assembled. Be sure to leave some space from the wall, or you’ll struggle to install the top panel screws. The build quality is excellent, solid and truly commercial grade. The cushions and materials feel sturdy and professional. What matters most to me is the compact footprint. Since this is for my home gym, where I also have a Murphy bed, space efficiency is critical. I previously purchased a TKO glute machine, and the quality has been consistently impressive, living up to the brand’s reputation. I highly recommend this leg curl and extension machine.
