The reverse crunch is a core exercise performed by lying face-up and raising your hips and lower back with your abdominal muscles in a controlled manner. With proper form, reverse crunches can improve posture and build core strength, targeting muscles like the rectus abdominis, also known as the abdominal muscle or six-pack abs.
Reverse crunches and traditional crunches both work your core muscles, but there are a few key differences between the two exercises.

- __Movement pattern__: While the standard crunch requires lifting the upper body, the reverse crunch allows you to keep your upper back relaxed while lifting your lower body. This reverse crunch posture can increase stabilization and relieve tension in your neck.  
- __Muscle groups targeted__: Reverse crunches specifically target your lower abs, which can be difficult to activate during a traditional crunch. The reverse crunch can increase core strength by activating deep core muscles like the transverse abdominis muscle. For a variation that also works your external obliques, considering carefully twisting your hips at the top of the movement.
- __Range of motion__: The reverse crunch has a greater range of motion than the traditional crunch, allowing you to hinge your knees and hips more.
For reverse crunches, aim to complete 2–3 sets of 10–15 repetitions, focusing on maintaining good technique throughout all sets and repetitions.

1. Lie face-up on an exercise mat with your arms by your sides and your palms facing down. Your spine and pelvis should be in a neutral position. Your chin should remain tucked throughout the movement, as if you were holding an egg under your chin.
2. Engage your core, and lift your feet off the ground in order to bring your knees toward your chest. Your knees should be bent at a 90-degree angle directly over your hips. Pull your toes toward your shins. Your legs should stay in the same position throughout the entire movement. All repetitions should begin from this position.
3. While maintaining a neutral spine, engage your core, and lift your tailbone off the ground using your abdominals.Your pelvis should move closer to your ribcage while your knees should move closer toward your chest.
4. Pause for a second at the top of the movement.
5. For the downward movement, continue to engage your core, and slowly lower to the starting position until your spine and pelvis are back in contact with the mat.
If you have a previous or pre-existing health condition, consult your physician before beginning an exercise program. Proper exercise technique is essential to ensure the safety and effectiveness of an exercise program, but you may need to modify each exercise to attain optimal results based on your individual needs. Always select a weight that allows you to have full control of your body throughout the movement. When performing any exercise, pay close attention to your body, and stop immediately if you note pain or discomfort.

In order to see continual progress and build body strength, incorporate proper warm-ups, rest, and nutrition into your exercise program. Your results will ultimately be based on your ability to adequately recover from your workouts. Rest for 24 to 48 hours before training the same muscle groups to allow sufficient recovery.
