I used to work for my dad in his office, the very first “real” job I ever had, and his favorite joke was saying that I was getting the “secretary spread,” a delightfully insensitive term he used to poke fun at the stereotype of overweight office women with flat butts munching out of candy bowls all day.

If you sit for more than 6 hours a day, (think about work, driving, watching TV, surfing the internet- are you sitting right now?) here are some disturbing facts: your risk of heart disease is increased by up to 64 percent. You’re also more at risk for certain types of cancer. If kept up long enough, you’re shaving years of quality time off your life. Sitting is literally killing you. Want one more scary fact? Most people sit for 15 hours a day.
