8. Side Lunges: Position both palms on your desk about shoulder-width apart. Push your left leg out and bend your knee to lower yourself to your left. Your right leg needs to be straight. Get back up and repeat for the other side.
9. Knee Tucks: Sit on the chair and keep your palms on the edge. Extend your legs in front of you and in the air. At once, bend your knees and pull them closer to your chest while keeping your back straight. Get back to the initial position and repeat. This is beneficial for your abs and glutes.
Apart from these exercises and stretches, some other changes that you can make in your daily routine include taking the stairs whenever possible, walk to get yourself a glass of water, walk a few steps while you are on the phone etc. Happy working!
