"My sister, for one, gets up before 6, has to get her two kids ready to school, leave the house by 7 to drive them to daycare and get them to work on time; get home at 6 or so if the traffic cooperates, shop, cook dinner, help them with their homework and show an interest in their lives, pay the bills, run errands..."
I mean no disrespect to your sister, but I also do all that. I get up at 5:25, walk the dog, get myself ready, get my daughter up and ready, fed, packed and out the door at 7:30, drop her at the before-school care program at school, go to work, pick her up at the after-school care program, come home, make dinner, help her with homework, do laundry, make lunches, get her ready for bed and into bed, and THEN I work out. For an hour. I know that 8 p.m. isn't the most ideal time to work out, but it's when I can fit it in, so that's when it happens. I wouldn't be worth living with without my exercise.
And people? I was KIDDING about the Doritos and the TV.
