Exercises for the core are crucial, particularly if you’re stuck sitting most of the day.
Nearly any core exercise you can think of can be adapted to do while sitting at your desk, and your swivel chair becomes gym equipment.
The benefits may be slightly diminished in some cases, but the efforts will help you to avoid back pain, and trim off belly fat.
Sit upright in your chair with your feet hovering about an inch over the floor.
Hold onto the edge of your desk, tighten your abs, and then use those abs to twist and swivel from side to side.
