Common Reverse Crunch Mistakes

The most common mistake is lowering the knees too fast. A few problems arise when this happens.

First, you’ll tend to hyperextend your lumbar spine.

Second, you miss the miss the most import portion of the exercise. The negative portion of an exercise is where most of the magic happens.

Muscles Worked in The Reverse Crunch

Like other crunch variations, the Reverse Crunch works all the major ab muscles.

The primary core muscle involved is the rectus abdominis. It’s the large muscle that you see when you have awesome six-pack abs.

Secondary muscles:

  • Obliques – the muscles on either side of the rectus abdominis.
  • Tranverse abdominis – the deepest of all abdominal muscles
