Question

Your friend isn't convinced her workout should include bone strengthening exercises and she question spending time and energy on them what should you tell her?

Answer 1

You should tell her that bones are very important, muscles aren't really anything if you don't have any bone strength.

Answer 2

Bones and muscles together form the supporting structure of the human body. If bones get weak, muscle performance will be affected and vice versa. So I would tell her that bone-building exercises are as important as muscle-building exercises. The difference is that muscle exercise makes a noticeable aesthetic difference, so people prefer it, but this is only possible with a strong bone support.
