Many of us try doing half push ups over and over again, but still are not able to get it. That might be because of lack of strength in the chest muscles. So, before trying the half push-ups that is a modified push-ups' form, you can try wall push-ups to strengthen your shoulders and arms to make the half push-ups happen.
WALL PUSH-ups are the easier version of the traditional push-ups, and are a perfect choice for a beginner. The regular push-ups help to strengthen the chest, arm and shoulder muscles, but wall push-ups are confined only to strengthen the chest muscles.
Let us see how to do wall push-ups to strengthen the muscles of your chest. Stand before the wall and maintain one arm distance from it. Lift your arms to your shoulder levels and keep your palm against the wall in such a way that your fingertips are pointing upwards. Keep your legs a couple feet away from the wall and stand on your toes.
This is the starting position of your wall push-up; make sure that your abdomen is tucked in and see that your ankle, hip and shoulders are in a straight line. And, now from this position just come down and move up. Inhale as you move down and exhale as you move up.
The common mistake that will occur in this exercise is that you could push your hip back or you will be arching your back. If you do any of these, then the exercise will not be effective. So, maintain a neutral position and strengthen your chest muscles, as shown in this indiainteracts video.
