HOIST HD3100 BICEPS / TRICEPS MACHINE

HOIST HD-3100: Two Arm Exercises in One Station

The HOIST HD-3100 combines seated preacher curls and triceps extensions in one selectorized strength station, allowing facilities to offer two complementary arm exercises without dedicating floor space to separate machines. The bi-directional exercise arm accommodates both movements, while the preacher pad provides a supported position for focused biceps training. For users, the result is a straightforward way to work the front and back of the upper arms at the same station.

DUAL-FUNCTION ARM TRAINING

HOIST HD-3100: Adjustable for Different Users

The HOIST HD-3100 offers seven seat-pad positions to accommodate different user heights and preferred exercise setups. Multiple range-of-motion adjustments allow users to select a starting position appropriate for preacher curls or triceps extensions, making the station more adaptable in a shared fitness room. Facilities can also choose between standard and heavier weight-stack configurations to better match their training population. The selectorized design makes resistance changes convenient between users.

COMMERCIAL STRENGTH APPLICATIONS

HOIST HD-3100: A Practical Choice for Commercial Facilities

For commercial gyms, corporate wellness facilities, multifamily fitness rooms and training studios, the HOIST HD-3100 can broaden upper-body training options without requiring separate biceps and triceps stations. It can complement the HOIST HD-3200 Lat Pulldown/Mid Row and HOIST HD-3300 Chest/Shoulder Press in a balanced strength-training area. Facilities planning additional stations can explore our selectorized strength equipment. When planning the layout, consider access to the seat, adjustment points and weight stack, along with appropriate clearance for exercise movement and service.
