The main problem when doing core lifts is weak rectus abdominis muscles. To make it easier to understand the reason, we will divide the exercise into two phases:
In the first phase, the contraction of the rectus abdominis muscle pulls you forward.
First phase. muscleandmotion.com
When the lower part of the spine is lifted off the floor, the hip flexor muscles are involved in the work: the iliopsoas muscles, the rectus femoris (one of the heads of the quadriceps), the sartorius muscles, and the tendons of the wide fascia of the thigh. Due to them, the body bends at the hip joint, and you move into a sitting position.
Strong abdominal muscles twist the pelvis in the lifting phase so that the load from the lumbar spine is relieved and the exercise becomes safe.
What happens if your abs are weak? After the twisting phase, you cannot hold the core with the rectus abdominis muscles and try to rise with the hip flexors. The pelvis moves backward, the lower back flexes, and compression of the vertebrae is created. The iliopsoas muscle pulls the vertebrae forward, disrupting the neutral position of the spine, which negatively affects its health.
In reality, correct and incorrect techniques look something like this:
If you do several approaches incorrectly, you may feel pain in the lumbar spine. And if you already have back problems, then you will only exacerbate the situation.
Instead of lifting the body, do twists without lifting the lower back from the floor. This will protect the spine from injury and will strengthen the rectus abdominis muscles.
However, twisting has its own danger. This time we are talking about tension in the cervical spine. Some beginners push their necks forward a lot. Repeated repetitions of this exercise plus working at a computer with constant tension in the cervical spine - and training can turn into pain. But there is a way out.
When doing curls, try to keep your neck relaxed, do not pull your chin to your chest.
You can also replace the body raises with or pulling the knees to the chest while hanging on the horizontal bar.
If you slow down the repetition too much, you simply won't be able to stretch yourself with your hip flexors. In addition, slow body raises are a great option for working out the press. So he will strain much more than during fast or sudden movements.
There is an interesting variation on this exercise - a slow twist with arms above your head and straight legs. Lie on your back, straighten your legs, stretch your arms over your head and begin to twist, lifting the body. The goal is to complete the exercise as slowly as possible. After straightening, begin to descend, too, very slowly and, if possible, linger at the point where your muscles feel the most tension.
That's all. Do the exercises correctly, and you will protect yourself from injury in the gym and during.

In an exercise that lifts the upper torso on the back, the abdominal muscles act as mobilizers. It is helpful to include exercise options in any exercise program for developing your abdominal muscles. (Note: Inelastic extensor muscles of the back, such as the erector spine, will not allow for maximum contraction and full range of motion.)
Raising the upper torso while lying on your back with bent legs
Exercise characteristics
Brief description of the exercise
Lift your upper body slowly. Lift your shoulder blades off the floor, and leave the lower back still. Pause, return to starting position and repeat the exercise. (Keeping your arms crossed on your chest will make the exercise easier, but without the support of your head with your arms, unnecessary tension in your neck muscles will not be relieved.)

Brief description of the exercise
Lift your upper body slowly. Finish lifting and bending your torso by pulling your upper torso towards your knees. Pause, slowly lower yourself to the starting position and repeat the exercise.

Raising the body from a prone position
Raising the body from a prone position belongs to the category of additional. This is an isolated open circuit traction exercise, which involves the work of the athlete only with his own body weight. To complete it, an initial level of training is required at least, which does not exclude the inclusion of lifting the torso from a supine position in the program of bodybuilders with an advanced level of body pumping.
When performing this exercise, the abdominal, sternocleidomastoid, anterior dentate, rhomboid and lower part of the trapezius muscles work as a mobilizing and stabilizing muscle groups. Therefore, lifting the trunk from a prone position is standardly included in programs for the development of abdominal muscles.
The exercise can be performed in two basic leg positions. In both cases, it means lifting the body from a prone position with legs bent at the knees, however, depending on the level of training, fixation of the feet on the floor with the help of a partner or a projectile is used. We will talk about the technique of their implementation below.
The starting position that the athlete needs to take is lying on his back. In this case, the legs, as mentioned above, are bent at the knees. The athlete's arms should be behind the head and the neck should be kept in a neutral position. The abdominal muscles are constantly tense. The starting position is accepted.
For the direct implementation of the exercise, it is necessary, slowly lifting the shoulder blades from the floor, to raise the upper body. The movement does not touch the lower back. In the raised state, you need to gain a foothold for a few seconds, and then also slowly return to its original position. It is worth repeating that even in the starting position, the abdominal muscles must be tense, otherwise the effect of the exercise can be significantly reduced.
An important and often overlooked point is the correct position of the neck and arms. The neck muscles do not need to tense when lifting the trunk from a prone position. This has no effect other than the possibility of earning micro-fractures. That is why, when taking the starting position, the hands are placed under the neck. If you cross them over the chest, the exercise will take less strength, but some of the effect and support of the neck muscles will be lost.
Raising the torso from a supine position is often not popular among self-taught athletes. This is due to the fact that not everyone achieves the set results, although the number of approaches and repetitions significantly exceeds the recommended ones in the programs.
The point here is not at all in the individual physiology of the athlete's body, but in the high-quality performance of the exercise. In order to understand exactly what a mistake can be made, here are some basic recommendations for the correct training of the abdominal muscles. So:
This exercise is of the type in which the number of repetitions and approaches is far from the first place. It is much preferable to perform fewer lifts with unsecured feet, but slowly and with optimal muscle tension, than quickly, due to inertia, to complete all repetitions. In addition to the fact that this will not have an effect, when doing this, the likelihood of getting a back injury increases.
