1) Whilst standing hold a barbell with your hands slightly beyond shoulder width and your palms facing towards you.
Keep a slight bend in your knees, arch your back and push your chest out. Keep your feet at shoulder width.
2) Lift the barbell at shoulder level with your elbows at a 45° angle towards your body and your palms now facing forward. You want your wrist to form a straight line with your elbow.
Keep your shoulders pushed back, do not let them come forward. Keep your core tight.
3) Exhale and push the bar straight up until it is above your head. Do not fully extend your elbows and have a slight bend in them.
Once your arms are extended above your head press your shoulders up to lift the bar a bit more.
4) Inhale and slowly lower the bar back to your starting position - stop at about your collarbone or chin.
