This pose is similar to seated forward fold, and provides the same benefits. It also stretches your groin. Assume the same starting position as the forward fold, but slide the sole of your left foot against your right inner thigh. Keeping your right foot flexed, lower your left knee as far as you can into a half-butterfly position. Walk your hands down the sides of your right leg as you fold forward as far as you can with your torso. Hold for 8-10 breaths, and then slowly rise back up. Switch legs and repeat.
A sedentary lifestyle can lead to having weak and tight hip flexors as they are always in the shortened position. Tight hip flexors can lead to a limited range of motion, poor posture, lower back and hip pain, and even injuries. These muscles need to get a workout when you are standing and doing movements such as raising your leg to climb stairs, run, or ride a bicycle.
