Performing crunches

A common mistake when performing crunches is to jerk the head forward and make the exercise easier to complete.

This practice not only puts large amounts of strain on the muscles of the posterior neck but also reduces the effectiveness of the crunches. Lacing the fingers behind the head can encourage you to pull on your neck even more!
