The Seated Single Leg Hugging Knee Flexion is a bodyweight strength exercise that targets the knee flexors of the thigh — primarily the hamstrings — by drawing one knee toward the chest and performing a controlled flexion movement while seated. It requires no equipment and is well-suited for building hamstring strength and knee-joint stability in a low-impact, seated position.
Seated Single Leg Hugging Knee Flexion: So führst du sie aus
- 1Sit upright on a firm chair or bench with both feet flat on the floor, your spine tall, and your hands resting on the sides of the seat for light support.
- 2Engage your core to keep your torso stable and avoid rounding your lower back.
- 3Lift your right foot off the floor and bring your right knee up toward your chest.
- 4Wrap both hands around the back of your right thigh, just above the knee, to hug the leg gently in place — this is your starting position.
- 5From this position, slowly flex your knee, drawing your heel toward your glutes as far as your range of motion allows while keeping your thigh held against your chest.
- 6Pause briefly at the point of peak contraction, feeling the hamstrings engage.
- 7Slowly extend your lower leg back down to the starting position — shin roughly parallel to the floor — under full control.
- 8Complete all reps on the right leg, then switch sides and repeat with the left leg.
- 9Keep your upper body still and your core braced throughout; do not rock or use momentum to complete the movement.
Technik-Tipps
- Keep your grip on the back of the thigh light — its purpose is to stabilize the position, not to forcibly pull the leg in, which would shift the work away from the hamstrings.
- Move through the flexion and extension phases slowly, aiming for a 2-second descent on the return; this keeps the hamstrings under tension and improves strength gains.
- Sit toward the front edge of the seat so the working leg has full freedom to move without the chair blocking the range of motion.
- Maintain a neutral spine throughout — resist the urge to lean back as you flex, since trunk movement reduces the demand on the knee flexors.
- Breathe out as you flex the knee and breathe in as you extend it back to the start position.
Häufige Fehler
- Using momentum to swing the heel up: Kicking or swinging removes tension from the hamstrings and reduces the training stimulus; the movement should be slow and deliberate throughout.
- Letting the thigh drop during the flexion: If the knee dips down as you flex, the hamstrings lose their stretched starting position and the effective range of motion shortens significantly.
- Rounding the lower back: Slouching shifts the workload away from the target muscles and places unnecessary stress on the lumbar spine, especially when holding the leg close to the chest.
- Gripping too high on the thigh or squeezing too hard: Pressing into the knee joint or holding the thigh at a steep angle can restrict circulation and alter knee mechanics; keep the grip at mid-thigh and relaxed.
- Rushing through reps: Performing the exercise at high speed sacrifices muscle control and reduces time under tension, limiting both strength and stability benefits.
Häufig gestellte Fragen
What muscles does the Seated Single Leg Hugging Knee Flexion work?
The primary muscles worked are the knee flexors of the thigh — chiefly the hamstrings (biceps femoris, semitendinosus, and semimembranosus). The hip flexors assist in holding the thigh against the chest, and the core muscles engage isometrically to keep the torso upright throughout the movement.
Is the Seated Single Leg Hugging Knee Flexion good for beginners?
Yes. Because it uses only bodyweight and is performed seated, it is accessible to beginners and to those who cannot yet perform standing hamstring exercises. The seated position provides a stable base, making it easier to focus on proper form and controlled movement.
How many sets and reps should I do?
For general strength and muscle endurance, 2–3 sets of 10–15 reps per leg is a practical starting point. As the exercise becomes easier, you can slow the tempo further, add a longer pause at peak flexion, or progress to a more challenging hamstring exercise.
What is a good alternative if this exercise is too easy?
Once this bodyweight version feels easy, consider Nordic hamstring curls, lying leg curls with a resistance band, or Swiss ball hamstring curls. These variations increase resistance and range of motion, providing greater hamstring overload.
Can this exercise help with knee stability?
Strengthening the hamstrings through knee flexion exercises like this one contributes to better dynamic knee stability, since the hamstrings act as secondary stabilizers of the knee joint. However, if you have an existing knee injury, consult a healthcare professional before adding this or any knee flexion exercise to your routine.
