Seated Leg Curl

What matters on this model

• Loads the knee flexors from a stable seated position.
• The adjustable thigh pad fixes the legs so the thighs do not lift during effort.
• The lower roller adjusts through 9 positions for different shin lengths.
• The range-of-motion setting lets you choose a comfortable start point without painful stretching.
• The back pad adjusts through 7 positions to align the knees with the lever axis.

How to set up

1. Sit deep in the seat and adjust the back pad so your pelvis stays fixed and your knees line up with the lever axis.
2. Lower the thigh pad just above the knees. It should hold the legs down without painful pressure.
3. Place the lower roller on the lower shin, slightly above the heel. Use one of the 9 positions for your height.
4. Set the range of motion so the start position gives a light hamstring stretch without knee pain.
5. Choose a light first weight and check that the legs move in an arc without the pelvis shifting.

How to perform

1. Hold the handles and keep your back and pelvis against the pads.
2. Exhale and curl your legs, moving the roller down and back under the seat.
3. Pause briefly at the end range and feel the hamstrings contract.
4. Inhale and return the roller slowly without dropping the weight stack.
5. Keep the feet neutral and stop the set when the pelvis starts to lift or the motion becomes jerky.

Common mistakes

• Sitting too far from the axis, which makes the knee path feel unnatural.
• Leaving the thigh pad loose, so the thighs rise and the range becomes shorter.
• Using too much weight, which pulls the pelvis forward and reduces hamstring control.
• Letting the weight return too fast, which relaxes the muscles and makes the stack hit.
