It's a good book if you're concerned about falling and need a place to start and get motivation. It includes something for absolute beginners and people who'd like to do chair workouts. It is a little repetitive but I just skipped to the exercises since I'm already a regular exerciser. I learned about cross trainers, mountain climber exercises and a few other advanced ones. I feel like the book could've taken more from yoga and I was hoping for more balance specific exercises though. Vestibular exercises improved my balance in physical therapy the most. I agree with the reviewer who said QR codes probably aren't useful for most seniors.

These are excellent youtube channels for anyone, any issue, any strength goal:
