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.
The flexor muscles are used when bending forward at the waist. The flexor muscles are located in the cervical and lumbar spine.
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 quadriceps muscles are primarily involved in knee extension.
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.
your muscles are not streched out so they get used to not being used
Muscles within the brachium are responsible for the extension of the elbow. These muscles also work for the flexing of the arm as well.
The muscles used in the leg press exercise are your Quads primarily. Hamstring gets a good work out too.
The muscles involved in hip extension are the gluteus maximus, hamstrings, and adductor magnus.
There are five muscles worked when doing a triceps extension. The main muscle is, obviously, the triceps. Secondary muscles that are worked are the deltoid, pectorals major, latissimus dorsi, and teres major.
The muscles that produce extension of the finger joints and wrist are the extensor muscles. In the forearm, the specific extensor muscles responsible for extension of the fingers and wrist include the extensor digitorum and extensor carpi radialis muscles.
Back extension primarily works the muscles in the lower back, specifically the erector spinae muscles.
