If you want to look slim while sitting, check you posture constantly. Pretend there is a band that stretches from the bottom of your spine to the top of your head. Place your feet on the ground, hip-width apart, directly in front of you.
2. Keep the Knees Together
Sit down back straight with knees, ankles, and heels together. Place hands between thighs as if to grab hold, applying pressure outward. Use your adductor muscles to maintain legs in a closed position. Do the exercise at your own pace until you get used to it. Once use to the exercise increase repetitions to about 30 times each time.
