Sit on the machine seat with your back firmly against the backrest and your feet flat on the floor, about hip-width apart.
Adjust the seat height so that the handles are level with or just below the top of your shoulders.
Grasp the handles with a firm, comfortable grip, keeping your wrists straight and elbows slightly in front of your body (not flared directly out to the sides).
Brace your core gently to support your spine and maintain a neutral posture.
Press the handles upward in a smooth motion until your arms are nearly straight but not locked at the elbows.
Pause briefly at the top, feeling your shoulders and triceps working.
Lower the handles back down slowly and with control until your elbows are roughly level with your shoulders.
Complete repetitions as prescribed by your physiotherapist.
