Performing the: A Step-by-Step Tutorial Gironda Sternum Chin
Pull your body upwards by bending your elbows and squeezing your shoulder blades together, aim to touch your chest to the bar, not your chin, hence the name 'sternum chin'.
As you pull up, lean your head back slightly and arch your spine to ensure your chest touches the bar.
Hold at the top position for a moment to ensure maximum muscle contraction.
Slowly lower your body back down to the starting position, fully extending your arms and shoulders, and repeat the exercise as needed.
