Using incorrect form, such as relying on hands and arms instead of core muscles, can impact crunch effectiveness.
An incorrect way to perform the crunch with a twist exercise is to use the hands and arms to lift up instead of engaging the abdominals and hips. This improper technique can lead to ineffective targeting of the core muscles, potentially causing strain on the arms and shoulders.
Additionally, performing the exercise with feet flat on the ground is also incorrect as it may reduce the engagement of the core muscles, limiting the effectiveness of the exercise.
It is important to ensure proper form by engaging the core muscles and avoiding reliance on the hands and arms to lift up during the crunch with a twist exercise.
