An easy stretch you can do at your desk: put one leg one your desk and lean forward far enough to feel a slight stretch. Alternate between flexing your foot and pointing it for a few seconds. End on flexing your foot, bend forward further and hold it for 10 seconds, then switch legs.4. Side twists
For an ab workout: sit up straight and have your feet hovering above the floor. You can choose to either hold the edge of the desk and use your ab muscles to move the chair side to side or simply move your upper torso side to side. Do 10-15 repetitions.5. Back stretch
Another stretch: Sitting up straight, push your shoulder blades together. Hold for a few seconds.6. Wall sits
Time to get up from your desk! If there is some free wall space near you, do a wall sit. Put your back against the wall, bend your knees, and lower yourself into a sitting position. Hold this position for 15 seconds to a minute. Distracting yourself can help you hold it longer, try browsing the apps on your phone.7. Kickbacks
Stand behind your chair and hold it. Kick one foot back, aiming your heel towards the top of your thigh. Switch legs and do 20-30 reps.8. Pump and run
Sit upright in your chair. For 30 seconds, pump your arms above your head. Right after you finish that, quickly tap your feet on the floor – as if you are doing football drills. Do at least two more repetitions.
