L-Sit
Move · Resistance Training · Movement, Typed Supps
Straightening the legs is what makes it hard, because the further your feet are from your hips the more the position weighs.
Stage by stage
- Set-up (Scapulae depress to lift): Lower trapezius, serratus and triceps hold the body clear — real work, but rarely the limiter.
- Legs extend (Moment arm increases): Straightening the legs moves their mass away from the hip axis, which is the entire difficulty scale.
- Holding (Hip flexors at short length): Iliopsoas and rectus femoris hold shortened against poor leverage while blood flow is occluded.
- Weeks later (Hamstring length caps range): Insufficient extensibility tilts the pelvis or bends the knee before strength becomes the constraint.
Muscles trained
- Primary: abs, hip flexors
- Secondary: quads, shoulders, triceps
Intensity
3.5 METs (Calisthenics, light or moderate effort, general (e.g., back exercises), going up & down from floor (Taylor Code 150)).
Time to effect
- Weeks: Most beginners can only hold a tucked (bent-knee) version at first, since straight-leg holds demand considerably more hip flexor and core strength.
- Months: Progressing from a tuck to a full straight-leg L-sit is a realistic multi-month goal for most people training it consistently, as hip flexor and ab strength build together.

Common myth
"The L-sit is mainly a shoulder and tricep exercise since you're supporting your bodyweight on your hands." In reality: While the arms do support the body, the far greater limiter for most people is holding the legs straight and elevated — the abs and hip flexors are usually what fail first.
