B Lock the knees rigidly
C Keep spine comfortably neutral
D Lift heels from ground
Answer: C. Keep spine comfortably neutral. A controlled hinge maintains a comfortable, stable spine as the hips move backward.
Why use both legs in a strength plan?
A Avoid movement variety
B Guarantee equal strength
C Remove need for recovery
