L-Sit

L-Sit is an advanced compound static using bodyweight. It loads Abs.

Why this lift

The L-Sit is a advanced compound static lift. It primarily loads Abs. Triceps, Shoulders, Quadriceps help. You need bodyweight. Most programs place it near the start of a session, while you are fresh. You may also hear it called L-Sits.

Loaded carries, crunches, and the brace on every compound already train the abs. Extra core work is seasoning, not the meal. This one asks for control and existing strength. Skip it until the easier variations in this library feel solid.

Muscles worked

• Primary: Abs
• Secondary: Triceps, Shoulders, Quadriceps

Setup

• Set bodyweight and lock a neutral spine. Ribs down.

How to do it

1. Move or hold so Abs stay braced. No yanking on the neck.

Coaching cues

• Exhale as you work. Keep the pelvis quiet.

Common mistakes

• Yanking the head or yanking the lumbar spine. Shorten the range; slow down.

How to program it

Treat the L-Sit as a main lift: 3–5 working sets, add load or a rep when the last set still looks like the first. Leave isolation work for after.

If the L-Sit does not agree with you, Barbell Rollout trains Abs with a different setup.
