i am pretty sure that it is the last one. Eustress is seemed to be beneficial, and distress is seemed to be the opposite.

<span>This is true. If your muscles are stronger then your bones will lose less because they work together with muscles. An easy example can be your spine. If you have strong back muscles there's less chance that you will suffer from spine injury from things like falling or lifting heavy objects. Bone loss is the same in that domain.</span>
