Crunches are one of the “core” exercises to work your core! Pro tip: Keep your eyes fixed on a specific object or spot on the ceiling as you perform the crunches. This will help you avoid straining your neck.
Step By Step Instructions
Lying on your back, place the feet flat on the floor with knees bent at a 45-degree angle. Lift the arms off the ground, keeping them parallel to the torso.
Push your chest and head up toward the ceiling, pushing your lower back flat onto the floor. Keep your head and neck in line with the spine. Don’t let your chin touch your chest. Return to the starting position.
