Yeah, most of us work 8 hours, then lets add in 1 hour for commute. So now we have 6 hours, SIX, every day 5 days a week to do whatever we want. That includes 1 hour in the morning, eat some brekky/wash up. Okay 5 hours, lets be generous with dinner and count another hour, so now 4 hours. That's 4 hours every day 5 days a week and FIFTEEN on weekends. Where you could do squats while watching TV, take the family dog out, do some situps or pushups, even, GODFORBID, go to the gym.  Oh but people rather be lazy and just sit on their ass and eat snacks every evening. Oh, I'm too tired. GO TO BED THEN and wake up early and do shit.  Oh and single moms? NO EXCUSES. You have 15 hours a day.
