What do you maintain throughout both movements in the Femur Arcs exercise?

In the Femur Arcs exercise, maintaining a neutral back position is crucial for ensuring proper spinal alignment and stability throughout the movements. This position allows for optimal pelvis and lumbar spine positioning, helping to engage the core effectively while avoiding strain on the lower back. A neutral back ensures that the movement remains controlled and centered, facilitating an effective range of motion in the hips while promoting overall body awareness.

Achieving and sustaining a neutral spine allows the practitioner to focus on the movement of the femurs (thigh bones) without compromising the integrity of the pelvic and spinal alignment. This is particularly important because any deviation from this neutral position could lead to compensatory movements that could cause discomfort or injury.

The other options pertain to aspects that don't align with the key focus of the Femur Arcs exercise. For instance, the legs touching the floor is not a requirement of the movement, nor is it functional to have feet positioned far apart or knees locked in place, as these do not promote the fluidity and control necessary for this exercise. Instead, keeping a neutral back allows for a safe and effective practice.
