Reverse crunches are a safe and accessible exercise that work the entire rectus abdominis without additional equipment. They can improve posture, strengthen oblique muscles, and prevent back problems. To perform, lie down and bring knees towards the chest, contracting abdominal muscles to lift hips off the floor. Additional equipment can be used for added intensity.
Unlike a sit up, a reverse crunch is an exercise used to train the abdominal muscles. Considered a safer alternative to the squat, the reverse crunch works your entire rectus abdominis, the long muscle that makes up your upper and lower abdomen. With no additional weights or equipment required, reverse crunches are an accessible exercise for most people.
People choose the reverse crunch as an alternative to crunches for a variety of reasons. They may have poor posture, which can be exacerbated by doing sit-ups. They may also experience back pain during squats, or suffer from a tight hip flexor, which can be aggravated by squatting.
Reverse crunches can help improve these problems. Movement can not only help correct posture; You can also strengthen the oblique muscles and correct lordosis, or an inward curvature of the vertebrae, by tilting the pelvis correctly. The reverse crunch can help prevent kyphosis, or rounding of the upper back, by keeping your ribcage aligned during your workout. Reverse crunches are a popular way to achieve the six-pack abs that many people strive for.
To do a reverse crunch, lie down on the floor. Hands should be placed on the floor or behind the head. Bring your knees in toward your chest, bending them to a 90-degree angle. Feet should be crossed or together. The abdominal muscles must contract to allow the hips to curl off the floor in a very small movement as the legs rise toward the ceiling.
After lowering the legs, the exercise can be repeated. Twelve to sixteen repetitions are recommended. Avoid swinging your legs to create momentum; instead, use your abdominal muscles to lift your hips for the best workout. During each rep, your lower back should push into the floor; The hands must not be able to fit behind the back during the movement.
The feet must remain low during the movement, just like the head; they need to go up when working the abdominal muscles. The knees should be bent, moving up towards the head; the head should not move towards the knees. The lower back should not arch, which can cause pain; rather, the pelvis should tilt during each repetition as the lower back is pushed into the floor.
Although not necessary, additional equipment can add intensity to your workout. A weight or medicine ball can be used as a counterweight during the movement. As the abdominal muscles get stronger, the counterweight can be lowered to create more challenges.
