Both of these exercises can be done at your desk and should only require a total of about two minutes.
Step 1: Turn your chair so that your legs are next to your desk instead of under your desk.
Step 2: Sit up straight, your knees should be bent at right angles, and your feet should be hip-distance apart.
Step 3: Hold your hands together in front of your chest.
Step 4: Exhale, and bend at your waist to the right, lowering your right rib toward your right hipbone while squeezing your abdominal muscles.
Step 5: Inhale and sit up straight again.
Step 6: Same technique - this time bending to the left side.
Repeat, switching sides, for one minute.
Step 1: Sit in same position as steps 1 and 2 above.
Step 2: Hold a closed water bottle, stapler, or some other handy object in both hands, above your head.
Step 3: Twist your torso toward the right, as far as you can, while squeezing your abdominal muscles.
