Office Chair Leg Raise in Sitting Position
The office chair leg raise in sitting position is a leg strength exercise suitable for practicing during working hours, mainly enhancing knee stability and providing targeted training for the quadriceps femoris.

Basic Movement Instructions
Sit on one-half or one-third of the chair to leave enough space for leg movement while ensuring good stability of the body during the exercise. Keep your upper body in an upright sitting posture with a straight back and do not lean against the chair back. You can place your hands naturally on the sides of your body to hold the chair edges or on your thighs. This posture helps maintain body balance and prevents injuries caused by body swaying during leg raising. Raise your legs alternately and slowly, keeping the movement steady. The angle and height should be within your comfortable range. Lift and lower your legs gently to avoid sudden lifting and retracting. Rapid and intense movements may cause damage to joints such as the knees, while steady and slow movements can better stimulate the quadriceps femoris and achieve the training effect. Try to keep your upper body upright and not move randomly, only performing the leg-raising action alternately. This concentrates the force on the legs and improves the targeting of the training. Coordinate with the natural breathing rhythm, using the method of inhaling through the nose and exhaling through the mouth. The standard is to feel slightly warm during the process without panting heavily or feeling palpitations. Reasonable breathing provides sufficient oxygen to the body and ensures the smooth progress of the movement. A complete set lasts for fifteen to twenty minutes. This duration can ensure a certain amount of training while not causing excessive fatigue to the body due to a too-long time.
Variant Movement Instructions
Variant movement of the single-leg leg raise in sitting position: Sit on a flat chair, place one leg on the chair with the knee straight and locked, and keep the other leg suspended and also straight with force. Keep your back and waist straight and slightly round your shoulders. Move the outer leg up quickly and down slowly. The up-quickly-and-down-slowly movement method can better exercise the leg strength of the hip flexors and stretch the lower limb muscles without putting pressure on the knees. If you find it difficult to complete the movement and feel tense in your body, you can lean back slightly. This can adjust your body's center of gravity, reduce the pressure on your legs, and make the movement easier to perform.
