The full press-up is one of the classic upper body exercises.
It continues to be used by elite athletes and is a simple and effective way of working your shoulders and chest.
Place your hands underneath your shoulders with your arms fully extended and your fingers facing forward.
Bend your arms at your elbows, lowering your chest until it is two inches above the floor and your elbows reach 90 degrees.
Try to avoid sticking your bum in the air and make sure your rhythm is smooth.
