A client can lower a leg press farther only by lifting the pelvis from the pad. What should limit the working depth?
- ALighten the load and keep the current depth
- BEnd each rep just before the low back begins to round
- CKeep the depth but brace the abdominals harder
- DSlow the lowering tempo so the pelvis can settle

Answer
B
The working depth should end where the pelvis and low back stay supported; the point where the pelvis lifts marks the client's controllable range.
A
Less load reduces force, but the pelvis still lifts at the same depth because hip flexion range, not load, is the limit.
C
Bracing helps trunk control but does not stop posterior pelvic tilt once hip flexion runs out.
D
A slower tempo changes speed, not range; the pelvis still rolls off the pad at the bottom.
B
The working depth should end where the pelvis and low back stay supported; the point where the pelvis lifts marks the client's controllable range.
