legs, arms, and back muslces
The quadriceps muscles are primarily involved in knee extension.
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 involved in hip extension are the gluteus maximus, hamstrings, and adductor magnus.
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.

The primary muscles involved in hip extension are the gluteus maximus and the hamstrings. The primary muscles involved in knee flexion are the hamstrings and the gastrocnemius.
An agonist muscle is a muscle that plays a part in the extension of a muscle. The agonist muscles for a knee extension are the quadriceps and hamstrings.
When using a back extension machine, the correct form to use involves keeping your back straight, engaging your core muscles, and bending at the hips while maintaining a controlled movement.
The back extension exercise strengthens and tones the muscles in your lower back, helping to improve posture and reduce the risk of back pain.
Sticking out your tongue primarily involves the use of about 8 muscles. These include intrinsic muscles, which change the shape of the tongue, and extrinsic muscles, which control its position. The main extrinsic muscles involved are the genioglossus, hyoglossus, and styloglossus. Together, they allow for the movement and extension of the tongue.
