Rock the Baby: Great antidote for sitting all day
Sit in a chair, keeping your back as straight as possible, and bring your right leg up, holding your foot in your left hand and knee in your right hand. Try lifting your calf so it's parallel to the floor and even with your chest, but don't worry if you can't. Simply hold the leg like a baby, and rock it back and forth for 20 to 30 seconds. Switch legs.
