1 Arm Press Up

One arm press ups place excessive strain on your body, not only around your shoulder joint on the arm being worked, but also on your lower back as you twist and rotate during the lifting / lowering phase.

START FULL POSITION	FINISH

START 3/4 POSITION	FINISH

With this in mind, I would not recommend performing this movement, however will show the safest way to prevent injury, in order for those that wish to utilize the benefits of this exercise - namely it looks good.

Avoid jumping straight into the movement, begin by performing in a wide knee stance three quarter press up position. You will want to have your knee wide to help balance your body, as this is why the exercise is so difficult, its not only your bodyweight you're lifting, your forced to fix your position in order to avoid total collapse.

You can use your spare arm in two ways, firstly to extend out to your side to aid balance, or by placing on the outer side of your leg, you can aid in the lift by pushing inwards with the arm.

Its essential that your feet are spread wide in order to help stabilize yourself, with your working arm placed slightly wider than shoulder width.

On the lowering phase, keeping your opposite shoulder high will reduce the workload on your bent arm, however will show the effect best on your working arm side.

My advice, avoid the risk of injury, perform a variety of different press ups to work your complete upper body, rather than one method which even though requires great strength to perform correctly, will certainly leave your muscles and joints feeling sore and tender.
