Crossfit Trainer Practice Test Level 1

What should not happen at the top of a pull-up?

1. Chin below the bar

2. Knees touching the ground

3. Eyes looking down

4. Chest pressing forward

The correct answer is: Chin below the bar

At the top of a pull-up, proper form dictates that the chin should be above the bar. This position indicates that the athlete has successfully completed the pull-up by engaging the necessary muscle groups effectively. If the chin is below the bar, it suggests that the movement was not executed to full range of motion, which is essential for both strength development and achieving the goals of the exercise. The other options relate to aspects of body positioning that can occur, but they do not directly indicate improper execution of the pull-up. Knees touching the ground does not apply as pull-ups are typically performed while hanging from a bar. Looking down may occur naturally during the movement, particularly if an athlete is focusing on form, but it is not indicative of whether the pull-up has been completed correctly. Lastly, the chest pressing forward can happen as a part of the movement but is not the primary focus at the top of the pull-up. The main concern at that point is achieving the chin above the bar for a proper completion of the exercise.
