Is a hanging leg raise trunk flexion?

Yes, a hanging leg raise is technically trunk flexion. Hanging leg raises involve lifting your legs, but the primary movement occurs at the hips rather than the knees or ankles. When you raise your legs, your torso must also flex (bend) forward to maintain balance.

Here's a breakdown:

- Trunk Flexion: Trunk flexion is the forward bending movement of the torso at the waist.

- Hanging Leg Raise: In this exercise, you hang from a bar and lift your legs straight out in front of you, keeping your body in a straight line. As you raise your legs, your torso bends forward at the hip joint to counterbalance the weight of your legs and maintain stability.

So, while the focus of the exercise is on lifting the legs, the trunk flexion component is essential to execute the movement properly.
