Common errors in using belly curling machines and rotary machines

Common use errors in belly curling machines and machines

　　Abs crunch machine)

　　As soon as many people sit on this type of equipment, they just adjust the weight, and do it up and down, completely ignoring the height of the seat and whether the entire movement is appropriate.

　　If there is a rubber pad in front, the height of the rubber pad should be just below the sternum, and the seat should also be adjusted. It is best to lean back slightly at the beginning of the movement. If the body leans forward at the beginning of the movement, the entire movement may cause the back bone to be too flexed, which may easily cause the back injury and the lower back. There is a problem with the body posture.

　　If you have a pair of handles to take you down for a curl, it is best to choose the one with a slightly tilted backward tilt. Of course, the seating height is also adjusted as above.

　　In addition to the correct way of using a curl machine, it is best not to rely on a curl machine for training the abdomen, because the curl is more aimed at the upper abdomen. If you do not perform other training exercises, the lower abdomen and side abdomen (Obliques) will be ignored

　　Torso rotation machine)

　　This error really has to be mentioned. Please! If you make a discus impact sound when using it, you will almost certainly be used incorrectly! Because this kind of device is usually used with a fixed tension range (Resistance curve), which is about 45 degrees to 90 degrees, which is definitely not allowing you to rotate left and right 180 degrees.

　　The position of the discus impact is the end of the tension range (Resistance curve). If you continue to turn, you actually have no effective tension at all.
