22:36, thanks. I'll check it out.
I take walks during the week which I consider my cardio. But I've read that strength can be far more effective than cardio, so that's what I want to focus on. I don't have much time but I want to figure out what I can do at home, in about 20 minutes. I was thinking some squats, crunches, pushups. I am overweight all over, but particularly in my belly (had a baby so this area is a mess), thighs, butt and arms.
