Crunch Exercise (Sit-Up)
The sit-up is a simple yet effective exercise that targets the abdominal muscles. It is commonly performed during sports activities or physical education classes. This movement strengthens our torso and improves our posture. Performing sit-ups helps us maintain balance while playing, jumping, or running.
How Do Our Abdominal Muscles Work?
During a sit-up, the muscles located at the upper part of our abdomen contract. These muscles enable our torso to bend forward. The muscles on the sides of our body help us move sideways. Together, all these muscles provide us with strength and stability.
How to Perform a Sit-Up?
- First, lie on your back on the floor.
- Bend your knees and place your feet flat on the ground.
- Place your hands behind your head or on your chest.
- Lift your head and shoulders upward, then slowly lower them back to the floor.
Attention! We must perform the movement slowly and correctly without straining our neck. Initially, five to ten repetitions are sufficient.
