The primary muscle used in push-ups is the pectoralis major. Its insertion point is primarily on the humerus (the bone of the upper arm), specifically at the lateral lip of the bicipital groove. This positioning allows the muscle to facilitate the pushing motion during the exercise, effectively engaging the chest, shoulders, and triceps.
The primary muscle attached at the point of insertion is the muscle that undergoes the most movement when the muscle contracts. For example, in the bicep curl exercise, the bicep muscle is the primary muscle attached at its point of insertion on the radius bone in the forearm.
The triceps muscle is the primary muscle used in a cable extension.

The primary muscle used in the seated calf raise is the soleus muscle. The insertion of the soleus is at the posterior surface of the calcaneus via the Achilles tendon. This muscle plays a crucial role in plantar flexion of the foot, particularly during activities that involve bending the knee.
the heel, in particular the calcaneus. the joint utilised being the tibiotalar joint.
The primary muscle group used in lunges is the quadriceps, hamstrings, and gluteus maximus. These muscles commonly insert at the tibia via the patellar tendon for the quadriceps, while the hamstrings insert at the tibia and fibula. The gluteus maximus primarily inserts on the femur and the iliotibial band. These insertion points facilitate knee and hip extension during the lunge movement.
The primary muscle targeted in lunges is the quadriceps, specifically the rectus femoris, which is one of the four muscles in the quadriceps group. The insertion point for the rectus femoris is at the patellar tendon, which connects to the patella (kneecap) and extends to the tibia. Additionally, lunges also engage the gluteus maximus and hamstrings, contributing to overall lower body strength and stability.

The Zygomaticus is the primary muscle used in smiling.

Criteria used to name the muscle, transverse abdomis was 1. Direction of the muscle fibers 2. Relative size of the muscle to the muscles around it 3. Location of the muscle 4. Number of origins 5. Location of the muscle's origin and insertion 6. Shape of the muscle 7. Action of the muscle
