knee extension and hip flexion
I would say that the rectus abdominis would be the main muscle associated with trunk flexion, but the external and internal obliques also perform trunk flexion.
your rectus abdominis is the prime mover in a crunch exercise or spinal flexion
Shuttle run is a type of exercise that is used mostly by athletes and coaches. The muscles this exercise uses is the rectus femoris; a quadricep muscle.
The V-sit exercise primarily works the abdominal muscles, including the rectus abdominis and obliques, as well as the hip flexors.
During a side plank rotation exercise, the muscles worked include the obliques, rectus abdominis, and the muscles of the shoulders and back.
You can choose four of the six: Superior rectus, Inferior rectus, Medical rectus, Lateral rectus, Superior Oblique and Inferior Oblique.
To effectively train the rectus femoris muscle, you can do exercises like squats, lunges, leg presses, and leg extensions. These exercises target the quadriceps muscles, including the rectus femoris. It's important to perform these exercises with proper form and gradually increase the weight or resistance to challenge the muscle and promote growth. Consistent training and incorporating a variety of exercises will help strengthen and develop the rectus femoris muscle.
The muscles are called the extraocular muscules, and they are the superior rectus, inferior rectus, medial rectus, lateral rectus, superior oblique, and inferior oblique.
The Rectus Abdominis helps your posture.

The quadriceps perform knee extension, however, the rectus femoris, which is one of the 4 muscles of the quadriceps, also does hip flexion.
During the plank pull through exercise, the muscles primarily worked are the core muscles, including the rectus abdominis, obliques, and transverse abdominis. Additionally, the exercise also engages the muscles in the shoulders, chest, and arms.
