How to and step by step instructions:

  1. Hold the chair arms and extend your elbows so that your butt stays off the chair.
  2. Bend your knees as if you were normally seated.
  3. Keep the upper part of the legs horizontal, from hips to the knees.

Hints & tips:

  • Good preparation for shoulders and abs.
  • When starting, to be able to hold the position for a few seconds is already a good exercise.
  • Exercise is office-friendly and can be done everywhere as long as the chair arms are strong enough.


  • Overall strength, focus on shoulders and abs.

Counting & gamification:

  • Count the seconds you can hold, accumulating in a period (session, day, week).
  • Set an accumulated goal for a workout session, say 60 seconds, and do the necessary repetitions to reach that goal.
  • Count accumulated time with this Half L Sit exercise, along with L Sit tuck in the floor, chair or pair of chairs.
  • Get used to try this position every time you sit on a strong chair. It will become easier and easier.
