I dont know how well this counts, or if it even does, but I like to think it does but when I do things like load and unload the washer/dryer (front loads) and the dishwasher, and putting stuff in lower cabinets. I do it in squat form. While I am hand washing dishes or working on stuff at the island, or reaching up to upper cabinets, I do it calf raise style.
I also do a "bathroom set". I am usually not missed for the few minutes it takes to do a set of squats, calf raises, and wall pushups. I usually do the calf raises while washing and drying my hands. I drink alot of water, so I have lots of opportunities to do those, though I don't do them every time.
