Which exercise increases axial bone mineral density MOST?

• A. Deadlift
• B. Barbell Shoulder Press
• C. Leg Press
• D. Back Squat

Answer: (B)

When bone adapts to loading, the spine responds most to vertical, compressive forces that stress the axial skeleton. That osteogenic stimulus is strongest when you place heavy load directly through the spine during weight-bearing lifts. Among the options, the back squat tends to produce the greatest axial loading on the spine. The bar rests on the upper back and you drive the weight upward through the hips and legs while the spine sustains substantial compressive forces. This substantial spinal loading promotes greater bone remodeling in the vertebrae, boosting axial bone mineral density the most. The leg press loads the legs with the torso supported, so spinal compression is reduced; the barbell shoulder press loads the upper body but with less sustained axial spine compression than a squat; and while a deadlift also places substantial load through the spine, the back squat often provides the higher and more consistent axial spine stimulus in typical training.
