L-Sit Pull-Up
The L-sit pull-up is a strict pull-up performed while you hold both legs straight out at hip height for the whole set. It trains the lats, upper back and biceps like a standard pull-up and adds a hard hip-flexor and abdominal hold, combining pulling strength and core work in one calisthenics skill.
Also called: L Pull-Up, L-Hang Pull-Up · Equipment: bodyweight · Pattern: pull
Step by step
- Hang from a pull-up bar with an overhand grip slightly wider than shoulder-width and your arms fully straight.
- Pull your shoulders slightly down away from your ears and brace your abs.
- Lift your straight legs to hip height so your body forms an L, with knees locked, toes pointed and legs together. If straight legs will not stay level, bend your knees into a tuck instead.
- Drive your elbows down towards your hips to pull your chin over the bar, keeping your legs level and still.
- Come back down under control until your arms are fully straight, holding the L the whole way.
- Start the next rep from a still hang, with no swing or kick.
- After the last rep, bring your legs down before letting go of the bar.
- Lock the L before the first pull
- Shoulders down, then elbows to your hips
- Legs level and still, no swing
- Ribs down, abs braced hard
- Chin over the bar, straight arms at the bottom

What goes wrong, and the fix
Legs dropping as you pull
Fix: Hold your legs at hip height from the first rep to the last; use a tuck if they drop.
Kipping or swinging
Fix: Start each rep from a still hang and pull smoothly with no leg drive.
Half reps at the bottom
Fix: Come down until your arms are fully straight before the next pull.
Chin short of the bar
Fix: Drive your elbows down to your sides until your chin clears the bar.
Shoulders shrugged in the hang
Fix: Pull your shoulders slightly down away from your ears before each rep.
What the research says
Sport performance · first choiceStrengthMuscle growthGeneral fitnessEndurance
- Muscles worked — EMG research on standard pull-ups shows the lats as the most active muscle, with the external obliques working at about a third of maximum. The held L adds a large hip-flexor and abdominal demand on top, which has not been measured directly.
- Load by goal — Research comparing loads finds maximal strength favours heavier loads, while muscle growth is similar across a wide range of loads taken close to failure. Because the L-hold limits reps and added weight, lifters focused on maximal pulling strength commonly use weighted pull-ups instead.
- Effort — Studies show sets that finish a few reps short of failure capture most of the size benefit, and strength gains appear largely insensitive to how close to failure you train.
- Volume and frequency — Research links more weekly sets for a muscle to more growth, with diminishing returns, and training a muscle about twice a week is a common way to spread that volume.
- Sets and reps — A common approach is 3–5 sets of 3–8 reps, ending each set when the legs can no longer hold hip height. There is no direct research on the L-sit pull-up.
