L-Sit Hold
The L-sit is a straight-arm support hold on parallettes, dip bars or the floor in which you hold both legs straight out at hip height, so your body forms an L. It trains the hip flexors, abs and triceps together with the muscles that pull the shoulders down, and is a foundational calisthenics skill.
Also called: L-Sit, L Hold, Parallette L-Sit · Equipment: bodyweight · Pattern: isolation
Step by step
- Set two parallettes just outside your hips and sit between them with your legs straight out in front. On the floor, place your hands flat beside your hips with fingers pointing forward.
- Grip the handles with your arms straight and your hands directly beside your hips.
- Push the handles down hard and pull your shoulders down away from your ears so your body lifts off the floor. Lock your elbows.
- Tilt your pelvis under, pull your ribs down and brace your abs.
- Lift your legs straight out to hip height with your knees locked, toes pointed and legs squeezed together. If straight legs will not stay level, hold a tuck with your knees drawn in towards your chest instead.
- Hold the position with your body high between your hands, breathing shallowly against the brace, for the target time.
- Set your feet down with control, then sit back down before releasing the handles.
- Push the floor away, shoulders down
- Elbows locked straight
- Ribs down, pelvis tucked under
- Knees locked, toes pointed
- Legs squeezed together at hip height
- Lift tall between your hands

What goes wrong, and the fix
Bent knees and sagging legs
Fix: Lock your knees and lift actively; hold a tuck until straight legs stay level.
Shoulders shrugged up
Fix: Push the floor away and pull your shoulders down away from your ears.
Elbows bending
Fix: Lock your elbows fully before your legs leave the floor.
Legs unable to reach hip height
Fix: Hold a tuck or one-leg-out L-sit and train pike flexibility alongside it.
Hips drifting behind the hands
Fix: Tuck your pelvis under, ribs down, and keep your hips level with your hands.
What the research says
StrengthGeneral fitnessSport performanceEndurance
- Holds — A common approach is 4–8 sets of 5–15-second holds at the hardest leg position you can hold cleanly, with full rest between sets. There is no direct research comparing L-sit hold durations.
- Isometric training — Reviews of isometric training find strength gains are specific to the joint angle trained. One review suggests holds of 3–30 seconds totalling roughly 80–150 seconds per session when muscle growth is the aim.
- Muscle length — A systematic review found isometrics held at long muscle lengths produced more growth than holds at short lengths. The L-sit holds the hip flexors and abs in a shortened position, so it is used more as a strength and skill hold than as a size builder.
- Muscles worked — EMG research shows the hip flexors are strongly active in exercises that lift the legs, more so than the abdominal wall, which is why the L-sit relies so heavily on the hip flexors.
- Frequency and building blocks — Many lifters practise it 2–4 times a week, early in a session, and build it with hanging leg raises, hollow-body holds, straight-arm support holds and pike flexibility work.
