All four groups are involved, but the motion to the sides is the transverse abdominal muscles.
There are several muscles in the human body that are not located above the waist. For example, the brevis and longus muscles are not above the waist, as they are located in the legs.
The flexor muscles are used when bending forward at the waist. The flexor muscles are located in the cervical and lumbar spine.
They are the same thing, but the word 'waist' is used more often in England, whereas 'twist' is heard more in America.
The muscles involved in bending forward at the waist are primarily the erector spinae muscles in the back, as well as the abdominal muscles and the hip flexors.
The human body contains over 600 muscles, with many located above the waist. Specifically, there are approximately 70 muscles in the upper body, which includes the muscles of the neck, shoulders, arms, chest, and back. This number can vary slightly depending on individual anatomy and how muscles are classified.
When you bend at the waist, you primarily use the muscles in your lower back (erector spinae muscles) and hamstrings. These muscles work together to support your spine and enable the bending movement. It is important to engage your core muscles as well to provide stability and protect your back.
Waist extension primarily involves the erector spinae muscles, which run along the spine and are responsible for extending and stabilizing the back. Additionally, the multifidus and semispinalis muscles also contribute to this movement by helping to extend and rotate the spine. The gluteus maximus may assist in waist extension, particularly when the movement involves the hip joint. Together, these muscles work to maintain posture and facilitate movements involving the lower back.
You should not bend down at the waist and lift up a heavy parcel using your back muscles. Always bend down at the knees, keep your back straight, and lift using your leg muscles.
Lots of meatloaf and mash potato.
be proud of your hips, first of all. We are women!!! But, don't try situps and crunches.. that works on the muscles, but not extra fluff fat. just do aerobic work, like running or jumping jacks. Is it fat or skin? try getting the skin tighter with gels, that could work. if you still try situps, do the ones where you twist to the sides.
I think you are asking about one of the My First Barbie ballerina dolls.
It should be "got her knickers in a twist." This is a funny idiom to refer to someone who is frustrated and angry. Think of how uncomfortable you would be if your underwear got all twisted up around your waist. In America, it's said as "got her panties in a twist."
