Decline Bench Crunch Benefits
It works your core muscles, squeezing them in a more intense way than other abdominal exercises. The decline crunch relies on the abs to push the body off the bench and so results in maximum contraction. For those who have become proficient in decline sit ups, adding some extra weights will help in maintaining the difficulty level.
