Which exercise can minimize hyperextension of the lower back during abdominal workouts?

Choosing feet unhooked, bent knee curl-ups is effective in minimizing hyperextension of the lower back during abdominal workouts because it allows for a more controlled and stabilized movement. When the feet are unhooked, there is less tendency for the pelvis to tilt excessively, which often contributes to hyperextension in the lumbar region. This position encourages proper form and ensures that the focus remains on engaging the abdominal muscles rather than relying on the hip flexors or risking undue stress on the lower back.

In contrast, other options may not provide the same level of support or alignment. A bent knee curl-up with feet anchored might create an opportunity for the lower back to engage in hyperextension, as the anchoring can facilitate an inappropriate pelvic tilt. Hanging leg raises, whether with or without back support, generally increase the demand on the hip flexors and may promote hyperextension due to the biomechanics involved in raising the legs while hanging. Thus, they are less ideal for targeting the abdominal muscles in a manner that protects the lower back.
