RussianAbout this machine
Leg curl isolates the hamstrings. It complements presses and squats, where the knee extends, by training knee flexion. Choose the version where you can keep the pelvis still and control the whole range without a jerk.
Muscles worked
- Main load: Hamstrings.
- Stabilization: trunk muscles help hold position.
- Should not hurt: joints or lower back. If they do, reduce load and check setup.
How to set up
- For the Pure Kraft Standing Leg Curl, first check its source-listed detail: uses a foot support or platform to fix the position.
- Set the roller just above the heel on the lower shin.
- Secure the thighs or torso so the pelvis cannot shift.
- Line the knee up with the lever pivot.
- Choose a range that does not force the knee into a harsh start position.
How to perform
Main exercise: standing leg curl.
- On the Pure Kraft Standing Leg Curl, move smoothly through this model's working path.
- Keep the pelvis still and avoid arching the lower back.
- Pause briefly at the end of the curl.
- Return slowly without dropping the weight stack.
Common mistakes
- Placing the roller too high on the calf or too low on the foot.
- Letting the pelvis lift or the body slide on the pad.
- Starting with a jerk instead of knee flexion.
- Letting the stack crash on the return.
- Ignoring this model-specific detail: uses a foot support or platform to fix the position.
