HOIST HD3600 AB CRUNCH / LOW BACK

HOIST HD-3600: Abdominal Crunch and Low Back Training in One Station

The HOIST HD-3600 combines abdominal crunch and low-back extension exercises in a single selectorized machine. These complementary movements give users options for training the front and back of the torso at one station. For facilities planning a balanced strength area, the dual-function design adds training variety while limiting the need for separate equipment. The abdominal-crunch movement emphasizes the front of the core, while the low-back movement trains the muscles that help extend and stabilize the spine. Keeping both exercises at one station helps facility operators offer complementary torso training without allocating floor space to two separate machines.

Unlike free-weight movements that require users to manage external plates, the selectorized resistance system allows quick weight changes between sets. This makes the HD-3600 especially practical for fitness clubs, corporate wellness centers and multi-housing gyms where many people share the same equipment.

DUAL-FUNCTION CORE TRAINING

HOIST HD-3600: Adjustable Setup for Shared Fitness Rooms

Seven seat-pad positions help accommodate users of different heights, while multiple range-of-motion settings allow each exercise to be configured separately. Angled foot pegs and horizontal foot pads provide different foot-placement options. These features make the station adaptable for shared facilities where users have varying preferences and exercise experience. The bi-directional exercise arm allows the station to change between the two core movements, while the adjustable range of motion helps users choose an appropriate starting position for each exercise.

For facility managers, the ability to accommodate different users at one station can make the strength circuit easier to navigate. Members can move between abdominal and lower-back exercises while keeping the familiar seat, weight stack and adjustment points. Proper setup and controlled movement remain important for both exercises.

COMMERCIAL STRENGTH APPLICATIONS

HOIST HD-3600: Round Out a Strength Circuit

The HOIST HD-3600 can complement lower-body stations such as the HOIST HD-3403 Leg Press/Calf Raise and HOIST HD-3400 Leg Extension/Leg Curl. Explore our selectorized strength equipment for additional options. The HOIST HD-3600 is available with a 180 lb standard weight stack or a 215 lb heavy-stack configuration, with an optional 5 lb upgrade for either version. Frame choices include Matte Black, Platinum and White, paired with Black upholstery. Facilities can select the configuration that best fits their training needs and room design.

In a complete commercial strength circuit, the HD-3600 adds a dedicated core station alongside upper-body presses, rows and lower-body equipment. Its dual-function design is particularly useful when floor space is limited or when operators want to offer a broader exercise selection without purchasing two separate torso machines. Before placing an order, consider the available stack option, expected member traffic and how the machine fits into your proposed equipment layout.

Ask an Equipment Specialist for help choosing commercial strength equipment.
