About

It's an effective workout for the entire core. However, if you do it incorrectly, it can hurt your back, so please fix it strongly with your thighs and do it in the correct posture!

How to Sit Up

Starting Position

1. Please lie on the floor with your knees up.

2. Place both hands in front of your forehead or support your head with your hands.

Proper Form

1. Please lift your upper body so that you can sit up straight.

2. Slowly return to the starting position.

Breathing Technique

Exhale when you lift your upper body, and inhale when you lower your upper body.

Precautions

If you have back issues, please avoid sit-ups and substitute them with crunches.
