Also known as: one-leg l-sit, one leg l sit, one-legged l-sit, parallettes one-leg hold
What is Single Leg L-sit?
The Single Leg L-sit is a static calisthenics hold on parallettes where you raise your hips and extend one leg while keeping the other knee tucked. It primarily targets the core and quadriceps and is rated medium difficulty - requires hip-flexor strength and shoulder stability.

How to Do Single Leg L-sit
- Set up parallettes: Place parallettes shoulder-width, hands under shoulders, neutral grip, arms straight. Ensure stable surface and engage triceps before initiating the lift.
- Get hollow position: Depress and protract scapula, round your lower back into a hollow body position while tucking knees tightly toward your chest.
- Lift hips and legs: Drive your shoulders down, press through hands, lift hips off parallettes and bring knees high before extending one leg forward into the L position.
- Extend one leg: Straighten and squeeze the quadriceps of one leg fully while keeping the other knee as high and tight to your chest as possible.
- Breathe and hold: Maintain hollow shape, breathe steadily, keep shoulders depressed and triceps engaged. Hold for targeted time, focus on core tension and leg alignment.
- Switch legs safely: Lower hips slightly, tuck knees, then extend the opposite leg. Reset hollow position and repeat to balance strength and reduce asymmetries.

Description
Take a neutral grip on the parallel bars, hands underneath your shoulders, arms straight, & triceps engaged.Depress & protract your scapula, round your back (drive your shoulder down away from your ears, and spread your shoulder blades)
Position your feet slightly in front of you, tuck your knees tightly, & raise them as close to your chest as possible.
From here extend one leg, while ensuring that the other knee stays as high as possible for the duration of the hold. Squeeze the quad of your extended leg, and try to keep that leg extended as high as you can, hold for time and then switch legs.

Frequently Asked Questions
What are the benefits of the Single Leg L-sit?
The Single Leg L-sit builds core strength, hip flexor and quadriceps endurance, and improves shoulder stability and scapular control. Practicing both sides reduces imbalances and transfers to improved compression strength for other calisthenics skills.
What common mistakes should I avoid with the Single Leg L-sit?
Common mistakes include letting shoulders shrug, failing to hollow the spine, lowering the tucked knee, and holding your breath. These reduce effectiveness and increase injury risk. Focus on shoulder depression, tight hollow position, and controlled breathing.
How can I progress to the full L-sit or regress this exercise?
To progress, increase hold time, practice both-leg L-sits, and work leg straightness plus hamstring mobility. Regress with tucked L-sits, seated L raises, or elevated single-leg holds with foot support to build strength safely.
