The video by Grokker expert Angelo Dela Cruz is the first video in his series on mobility that you might want to check out. It includes a few other practices that combine simple movements and stretches to better help with everyday mobility and balance. The next two videos I attached are some yoga practices that focus more on standing poses for help to improve balance through slower poses. These would be a good place to start. You can look up more videos by optimizing your search bar and if you find a practice you like, you can make a collection so that you can find those videos much faster. Here is a link from the Grokker Help Center on how to create collections https://support.grokker.com/hc/en-us/articles/360000164012-How-do-I-create-a-Collection-.
