Do not touch the floor with your chest. The descent should be controlled. Keep a 5-8 cm distance. To avoid mistakes, put a book on the floor while doing push-ups. When you touch the book with your chest, you will know it is time to get up again.2. Adrenalast If you are a beginner and traditional push-ups seem too hard, do knee push-ups instead. Start facedown on the ground, bend your knees so that your feet come off the ground, and cross your ankles. If knee push-ups are also too hard, do wall push-ups. Stand two feet from the wall and place your hands flat against it. Bend your arms slowly until your face is about 2 inches from the wall. Then push back and return to starting position.After a few days, you will certainly be able to do knee push-ups and then the basic pushups.http://www.strongmenmuscle.com/adrenalast/
