Product details
Hamstring training that keeps users in alignment
A leg curl set up wrong loses the hamstrings and stresses the knee. The Spirit SP-4306 Seated Leg Curl keeps the user aligned with the machine's axis of rotation, with a self-adjusting tibia pad that cuts the number of set-up changes needed.
Who it's for
Commercial gyms, hotel fitness centres, clubs, college gyms and rehab-oriented facilities that want a guided hamstring station.
Key benefits
The thigh pad adjusts to the front of the knees, keeping the user aligned with the axis of rotation. The lower tibia pad self-adjusts, limiting the number of necessary set-up changes. The range of motion is adjustable for users with limited hamstring flexibility. A 115 kg stack, integrated rep counter and top-cap storage complete the station.
