Question

if uriel wants to increase his bone density, what should he work on?

reaction time
speed
strength
coordination

Explanation:

Bone density is related to the strength and mass of bones. Strength - training exercises put stress on bones, which stimulates bone - forming cells. This stress causes bones to adapt by becoming stronger and denser. Reaction time, speed, and coordination are more related to nervous system function and muscle performance in terms of movement execution rather than directly affecting bone density.

Answer:

strength
