Isolation

About

It's the best workout to build up your upper abs, and is different from sit-ups. Try to keep your waist intact with the floor while doing the workout.

Coach's Tips

Anchor your feet to the floor and lie down with your knees bent.

Slowly roll up your upper body and focus on stimulating your abdomen.

How to Crunch

Starting Position

1. Lie down on the floor and bend your knees.

2. Lift your upper back and head off the floor.

Proper Form

1. Please lift your upper body while keeping your back 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

1. If you lift your upper body excessively, it can strain your lower back, so please lift your upper body without raising your back.

2. If your neck hurts, support your head with your hands and relax your neck while proceeding.
