I recently stumbled across this site thanks to a Washington Post article:
Squeeze It In
I'm not certain about this website. I haven't really been able to dig that deep. But from what I've seen, it does seem pretty promising.
The laundry squats does have a very good description of how to do a nice, deep squat (although it warns you about letting your knees go over your ankles...maybe they mean past the toes? Which still isn't an issue).
The countertop pushups are done with good form, too. So are the side planks done on an angle, which isn't a bad way to start for people for whom a full side plank is difficult.
The idea seems good, too - squeezing in some working out, taking away the "I don't have time" argument. It's interesting enough so I wanted to pass it along. Moms, what do you think? Are you going to add laundry squats into your weekly routine? I usually use the "upend the hamper over the washing machine" method, but that's pretty low-rep.
