Spending a lot of time at your desk is no excuse to miss out on getting the stomach you want. In fact, you can still strengthen and tone your abs by doing belly-blasting workouts in your chair. Try these exercises in the chair you’re sitting in right now!
Vertical crunches
Move forward to the edge of your chair and place your legs on the floor in a 90-degree angle at the knees. Engage your core. Keeping your lower body completely still, lean back in your chair until you almost touch the back of your chair. Hold the position, focusing on the muscles in your abdomen. Return to an upright stance.
Oblique twists
Sit on the edge of your chair again. Rest your feet flat on the floor and place your knees at right angles. Open your arms out to the side so that they are perpendicular to your body. Twist to the left and right, engaging your abdominals and keeping your back flat and straight. Twist to the right, hold the twist for about three seconds, then return to center, pause and repeat the twist to the left.
Sitting seesaws
From the same seated position as before, place your hands behind your neck. Lower your right elbow to your right hip. Bend your upper body sideways (but not forward or backward). You should feel a stretch on your left side. Hold for a few seconds, then return to center. Repeat the same movement with the left side.
Floating
Press your hands on the seat of your chair, gripping the edges for more stability. Shifting your weight to your arms and engaging your core, lift your thighs off the chair. Try to lift yourself about one to two inches off the chair. Hold the position for 10 seconds. Keep your back straight and your abdominals flexed to hold the position. Return to a straight seated position, rest and repeat the exercise again.
Core V’s
From a seated position on the edge of your chair, engage your core and bring your knees to your chest, leaning back slightly. Keep your back straight. Straighten your knees to point your feet upward. Balancing on your tailbone, the legs and body should form a “V” shape. Return to the initial position with knees to the chest, rest, and repeat.
Warning: For your safety, these exercises are not to be done in chairs on wheels!
