Crunch with hips flexed to 90 degrees and feet supported on elevation: Execution

The starting position sees the athlete lying supine on the floor or on a bench with the hips flexed at 90 ° and knees flexed so that both feet are resting on a rise, such as a chair, a bench (if lying on the floor) , or on a barbell (when lying on a flat bench press with a barbell). The lower limbs must remain motionless for the entire duration of the exercise. The head is initially in contact with the floor or bench. Hands can be held at the sides, crossed across the chest, at the sides of the head at the temples, or behind the head with shoulders fully flexed and elbows extended. The list was written in ascending order of difficulty. Once established where to position the limbs, it is no longer possible to change this parameter except as a cheating technique or to lighten the load during a “stripping” series. The execution consists in performing a spine flexion so that the upper back comes off the support surface, while the lower back remains in contact with the floor for the duration of the exercise. The distance between the chin and the breastbone should remain as constant as possible. The range of motion is reduced, as lifting the back too much ends up flexing the hip as well, turning the crunch into a sit-up. To emphasize the work of the oblique abdominals, it is possible to perform the concentric phase of the movement by twisting the torso towards the right side; in this movement the work of the external obliques of the left side and of the internal obliques of the right side is maximized. The movement is one-sided and the description refers to the right side. Repeat in a mirror image for the left side.
