This is the easiest part, but it also starts the arm wave, so get ready to let the movement flow through your arm! You can start the wave with either arm. However, it’s better to focus on 1 side first until you master the movement.
Practice this until you can transition smoothly from your fingers to your wrist. The rest of your wave should have similar a similar, smooth motion, so use it as a point of comparison.
Twisting your arm inwards helps you lift your elbow. However, keep your hand flat and make sure your shoulder doesn’t rise up towards your neck. This is most likely going to be the hardest part of the arm wave for you. Practice it until it feels natural.
Instead of moving your arm away to straighten it, try bringing your arm towards your body. Keep your arm straight as you move it. Leaning to the side or moving your arm back towards your ear is fine. Doing this can also help you lift your shoulder.
Pushing your chest out can make the transition easier. You can also roll your head a little in the direction of the wave to help get your shoulders moving. You left arm might feel pretty tired now. Normally you want to keep it up as you complete the wave, but you can drop it to rest it while you practice. For a more advanced wave, rotate your shoulder, bringing your arm forward as the wave motion moves to your other arm. Move your arms and other parts of your body each time.
Getting your elbow into position will most likely be the toughest part of the wave, so don’t worry if you can’t get it right away.
Keep your arm level with your shoulders as you finish the wave.
You can curl your fingers towards your palm while lifting them. This might help you master the wave movement. However, make sure you straighten them back out before your wrist lowers completely.
Once you have mastered doing the arm wave in 1 direction, try starting with your opposite hand. Also try waving with both arms at the same times or reversing the wave motion. For a variation on the arm wave, try rotating your shoulders forward. Keep your body still and hold your arms out in front of you at first. Try doing the wave with your arms in different positions, including with your fingers touching in front of you!
