Tuck L Sit

Lift your body into a tucked L position and hold it to work the abdominal muscles through an isometric hip-and-core contraction.

How to do the Tuck L Sit#

  1. Sit with your hands placed beside your hips and press your palms into the surface.
  2. Straighten your arms and lift your hips so your weight is supported by your hands.
  3. Draw your knees toward your chest and tuck your legs so your thighs are close to your torso while keeping your shins forward to form the tucked L shape.
  4. Maintain a tall chest and engaged core while breathing steadily throughout the hold.
  5. Lower your hips back down with control to exit the position.

Frequently asked questions#

What muscles does the Tuck L Sit work?

The Tuck L Sit primarily works the abs, hip flexors. The triceps, front delts, chest, lats assist as secondary muscles — they stabilise the movement and take over when the main target fatigues. If you feel it mostly in the triceps, front delts, chest, lats, lighten the load and slow the lowering phase.

What equipment do I need for the Tuck L Sit?

None. The Tuck L Sit is a bodyweight exercise, so all you need is enough space to move through the full range of motion.

Is the Tuck L Sit suitable for beginners?

Not as one of your first exercises. The Tuck L Sit is rated intermediate, so it suits lifters who already have a few months of consistent training behind them. Build the pattern on an easier variation first, then come back to it.

What are good alternatives to the Tuck L Sit?

Ab Coaster, Ab Wheel, Air Bike all train the same primary muscles as the Tuck L Sit. Pick whichever one matches the equipment in front of you.
