How to Perform

1. Set the pelvis and rib cage in a controlled starting position.
2. Initiate the movement from the trunk rather than pulling with the neck or using momentum.
3. Move through the intended range while maintaining abdominal tension.
4. Pause briefly at the shortened position.
5. Return slowly without losing control of the pelvis.

Coach Abuzaid Technique Cues

• Brace before the working phase.
• Use controlled range of motion.
• Keep the intended joints aligned.
• Stop the set before technique breaks down.

Common Mistakes

• Using momentum to replace muscular control.
• Rushing the lowering or recovery phase.
• Losing trunk or joint alignment.
• Continuing after technique has clearly deteriorated.

Benefits

• Develops capacity in rectus abdominis through a isolation pattern.
• Builds repeatable movement control and position awareness.
• Can be progressed through load, range, tempo, volume or complexity.
• Fits structured strength, hypertrophy, skill or conditioning work depending on how it is programmed.

When to Use It

Use Reverse Crunch when the program calls for a isolation pattern that emphasizes rectus abdominis. Adjust load, repetitions, rest and range to match the session goal rather than treating the exercise as a fixed prescription.

Safety Notes

• Use a load and range you can control with consistent technique.
• Keep the equipment setup secure before beginning the set.
• Do not force painful range or continue through sharp, sudden or unusual pain.
• Increase load or complexity only after the current variation is repeatable.
