Talk about each exercise; squats, lunges, glutes bridges, bent over rows, push-ups, and overhead press. Try to use images to show how they are performed and the benefits that come with doing that specific exercise.
Then make two separate guides: One to show how to perform those six exercises using dumbells. The second to show how to perform those same exercises using resistance bands. Try to use images if you can please. Let me know if you have any questions!
