The PUSH UP test
Get your phone and put a timer on for 30 seconds.
We will make a difference here between the female and male surfer. The men start from a full plank position, the women can place their knees on the floor. Your hands are on shoulder width. The push up will be performed until a depth that your chest touches the floor and with your elbows just next to your trunk. When you come back up, you do that by fully extending your elbow. Like that we use all the range of motion in our shoulders.
