Housework, laundry, gardening, get the car cleaned, yoga, swim, run, gym, meet friends, read, watch TV, sew, knit, other arts/crafts, weekend adult education, go to museums, art galleries, theatre, cinema, music, beach, dancing, walk in the country, cycle, go away for weekend to a new place, sometimes even go dating.
Not all of that in the same weekend, mind you!
