Hoist HD-3400 Dual Leg Extension / Leg Curl Overview

The Hoist HD Dual Series was designed for fitness facilities that need commercial-quality strength equipment while making efficient use of floor space and equipment budgets. The series combines multiple exercises into dual-function stations, allowing facilities to create a complete strength-training circuit with fewer individual machines.

The HD-3400 Dual Leg Extension / Leg Curl combines two of the most popular lower-body isolation exercises into one commercial machine. Users can strengthen the quadriceps with leg extensions and train the hamstrings with seated leg curls while benefiting from intuitive adjustments and comfortable body positioning.

Hoist incorporates the same attention to biomechanics, durability and styling found throughout its commercial strength equipment. The HD-3400 features a heavy-duty oval-tube frame, a commercial weight stack and convenient adjustment points designed to accommodate users of different sizes.

Comfortable and Easy to Adjust

The Hoist HD-3400 Leg Extension / Leg Curl is designed to accommodate a wide range of users. Eight back-pad adjustment positions make it easier to establish proper leg positioning, while multiple range-of-motion settings allow the machine to be configured for both leg extensions and leg curls.

A self-aligning roller pad automatically adjusts during exercise to help maintain comfortable positioning around the lower leg and ankle. The ratcheting seat adjustment system also allows users to quickly change positions without complicated setup procedures.

Commercial-Grade Construction

Built for demanding fitness environments, the HD-3400 uses a durable oval-tube steel frame designed for commercial strength training. Integrated scuff guards and rubber foot protectors help protect both the equipment and gym flooring.

The machine also features Hoist's Silent Steel® weight stack system, which is designed to provide a smoother and quieter training environment. These commercial components make the HD-3400 suitable for health clubs, hotels, apartment communities, corporate fitness centers, physical training facilities and premium home gyms.

Two Lower-Body Exercises in One Machine

Leg Extension

The leg extension exercise primarily targets the quadriceps muscles on the front of the thighs. Users sit against the back pad, position their lower legs behind the roller pad and extend their knees against the selected resistance.

Seated Leg Curl

The seated leg curl primarily targets the hamstring muscles on the back of the thighs. The machine's adjustable positioning allows users to transition from leg extensions to leg curls while using the same commercial weight stack.

Combining both exercises in one machine can help fitness facilities save valuable floor space compared with purchasing separate leg extension and leg curl stations.
