Step 2: Lift one foot off the ground and extend it forward, keeping it parallel to the ground.
Step 3: Bend your standing leg and lower your body down as if sitting back into a chair, keeping your chest up and your back straight.
Step 4: Lower yourself until your thigh is parallel to the ground, then push through your heel to return to the starting position.
Step 5: Repeat for the desired number of repetitions, then switch legs and repeat.
