putting keywords inside blog help other pages?

Hey... I am wondering if stuffing keywords inside blog posts will help rank other pages which are targeting that keyword? I.e. We have a page called chocolate protein shakes... which we are building links to rank. Will making a separate blog post on a different page with keyword "chocolate protein shakes" help rank the target page (page we are buildings links to)?

Do you want to make separate blog page in the same website? if yes you can but content should be different and fresh, use this keyword chocolate protein shakes in your new blog. But please do not do stuffing.

Stuffing keywords will not help you in any way nowadays.

Also, do some more reading on keyword cannibalisation, because that's exactly what would happen with this approach.
