Crunches are one of the most well-known abdominal exercises. When performed with good technique, they are a reliable way to build core strength and stability.
Instructions
- Lie flat on your back with your knees bent and feet flat on the floor or resting on a bench.
- Place your hands lightly at the sides of your head — don’t interlock your fingers.
- Engage your abs and press your lower back into the floor.
- Lift your shoulder blades off the ground by curling your torso up.
- Pause at the top, then slowly lower yourself back to the start.
- Focus on form and tension, not momentum.
