Stand tall with your feet hip-width apart and shoulders relaxed. Position yourself near a stable surface, such as a countertop or sturdy chair, for support if needed.
Engage your core muscles to maintain an upright posture and keep your gaze forward.
Slowly lift one knee towards hip height, or as high as comfortably possible, keeping your foot flexed and avoiding leaning backward.
Lower your foot back to the floor with control.
Repeat on the other side, alternating legs in a steady marching motion.
