Seated Leg Curl

Seated Leg Curl is a beginner-level isolation in the strength category that primarily works the hamstrings. It is performed with machine.

How to do it

1. 1Adjust the machine lever to fit your height and sit on the machine with your back against the back support pad.
2. 2Place the back of lower leg on top of padded lever (just a few inches under the calves) and secure the lap pad against your thighs, just above the knees. Then grasp the side handles on the machine as you point your toes straight (or you can also use any of the other two stances) and ensure that the legs are fully straight right in front of you. This will be your starting position.
3. 3As you exhale, pull the machine lever as far as possible to the back of your thighs by flexing at the knees. Keep your torso stationary at all times. Hold the contracted position for a second.
4. 4Slowly return to the starting position as you breathe in.
5. 5Repeat for the recommended amount of repetitions.

Tips and common mistakes

• •Focus on the muscle contraction and control the eccentric (lowering) phase.
• •Add load only once you complete all reps with good form — progressive overload.
• •Initiate the pull from the target muscle rather than jerking with body momentum.
• •Prioritize full range of motion over heavy weight with partial reps.

Sets and reps

For hypertrophy: 3–4 sets × 8–12 reps with 1–2 reps in reserve (RPE 7–9) and 1–2 minutes rest. For strength: 3–5 × 4–6 with longer rest.
