What activities, as a caregiver, do at home to relax, be centered, maintain friendships, workout?

I am needing to fit in more activities for my own self care, self development and I am looking for some at home ideas. I'd like to try to do what I can from home to maintain a sense of self in all of this...maintain friendships as I can, family connections, stay fit and more positive while caring for a parent. Parent will go to day program 4 or so hours/ day but beyond that any ideas for caring for myself while caregiving. What do you do as a caregiver to care for yourself? What have you fit into your routine or what would you like to fit into your routine?
