Criss Cross

Side, core strengthening
Criss Cross gif

About

Twist your sides and open your chest as much as possible. If the basic posture is difficult, put the soles of your feet on the ground and just raise your knees to workout!

How to Criss Cross

Starting Position

1. Please lie down comfortably on the floor.

2. Keep your legs straight and lift them to form a 45-degree angle with the ground.

3. Use both hands to support your head.

Proper Form

1. Lie on the floor and raise both legs towards the sky at a 60-degree angle while keeping them together.

2. Interlock your fingers behind your head and lift your head off the floor.

3. Keep your toes pointed and prepare by looking at your toes.

4. Bend your right elbow and think of it touching your left knee while bending your knee and folding your upper body.

5. Do the same on the opposite side.

Breathing Technique

Exhale while crossing your legs and inhale while returning to the original position.

Precautions

If it's difficult because it's a high-intensity exercise, please substitute it with another exercise.
