Office Chair Leg Extensions
Leg extensions are recommended anytime you're stuck in a sitting position for a while, like during a car ride or on a plane, says Guillem Gonzalez-Lomas, M.D., assistant professor of Orthopeadic Surgery at NYU Langone Medical Center. They're a great move for desk jockeys too, especially since you can do them discreetly at your own desk or even under a table in a conference room. Sit on the edge of your chair, back straight, arms at your sides. Extend one leg out, flexing your foot, and raise the leg until it's at a 90-degree angle with your torso. Hold, and then lower. Aim for three sets of 10-20 reps on each leg.
