STARTING POSITION:
Select the appropriate plates amount to put them on the bar. Grab the bar using a prone grip slightly wider than shoulder width apart. Lie on a fitball. Make sure you rest your upper back and your head on the fitball. Your feet should be touching the floor. Extend the elbows to lift the bar up and hold it straight over you with your arms locked.
MOVEMENT:
Lower the weight down slowly to the chest while you breath in. Push the bar back to the starting position while you exhale. Repeat the movement until all repetitions are completed.
TIPS: Focus on push the bar with your chest muscles and squeeze the glutes when you do it. If you are a beginner at this exercise, use a spotter. If no spotter is available, then be conservative with the load that you use.
