This exercise is used to give a greater range of motion to the standard floor press and will involve the shoulder muscles more.
Lie on the floor on your side with a kettlebell in one hand. Bend the leg that is on top so that you can better balance your body. Bend your arm so that your upper arm is supported by the floor and the kettlebell is facing away from your chest. Now, press the kettlebell by extending your elbow and also pulling your body closer to your body at the same time. Continue to press the kettlebell until your arm is fully extended over your body. Hold this position slightly and then return the kettlebell to the starting position. Repeat this movement until you have completed your set, and then repeat with the other arm.
This movement should not be performed until you have mastered the normal floor press. This movement can put more stress on your shoulders than the normal floor press.
