Personal trainer website

Hey guys,a friend of mine asked me to make a website for him, so I’ve put some dummy text and some pictures from unsplashed and I created the layout.
I am looking for some feedback before sending it to him, and hopefully some help on how to implement the parallax scrolling on the banners a little better. Any comment will help.Thank you so much guys!

This is the codepen project : https://codepen.io/marekiaro/full/ZvJQMj/

i have two suggestions that would make the appearance a little better:

  1. Change the font of the P’s into something a little more stylish.
  2. Make your navbar (that is now only at the top of the page) scroll down when the web-visitors scroll down by adding a fixed class to the navbar. This would make it easier to navigate. I think it is important for this website, because it is quite long.

Good luck, It looks very nice though!
