Setup
- Sit on the floor with your legs fully extended and feet together.
- Place your palms flat on the floor directly beside your hips.
- Point your fingers forward or slightly outward to reduce wrist strain.
- Engage your core and pull your shoulder blades down and back.
How to do it
- Exhale and press your palms aggressively into the floor, locking your elbows to lift your hips off the ground.
- Contract your quadriceps and hip flexors to lift your heels off the floor until your legs are parallel to the ground.
- Maintain the 'L' shape by pulling your hips slightly back between your arms.
- Hold the position for the prescribed time, taking shallow, controlled breaths to maintain intra-abdominal pressure.
Form checklist
- Keep your elbows fully locked out throughout the entire hold.
- Depress your shoulders (push them away from your ears) to maximize height.
- Keep your legs perfectly straight with knees locked and toes pointed.
- Ensure your hips are tucked back between your hands rather than hanging in front of them.
Pro tips
- Focus on 'pushing the floor away' to engage the serratus anterior and lower traps for better elevation.
- Squeeze your inner thighs and glutes together to create a rigid lower body, which makes the legs feel lighter.
- If you struggle to lift your heels, practice by lifting one leg at a time or using parallettes to gain extra clearance.
Make it harder
- V-Sit: Raise your legs higher than parallel, aiming for a 45-degree angle or higher.
- L-Sit Pulses: While holding the L-sit, pulse your legs upward in small, controlled movements to further tax the hip flexors.
