Show HN: Exercise programs for seniors and older adults over 50

How do you or your parents / grandparents typically exercise if you are 50? Research shows it is very important to build muscle to avoid joint pain and falls in the future. We wanted our parents to do the right types of exercise so found a few trainers who specialized in this and are putting together this program. Linked above is a free class we are hosting to learn more.

I'm curious if this is something you've struggled with and whether there are any other online resources that helped you?
