I could not agree more my friend. I hated pushups this week. Well. I hated the thought of doing pushups, but having done pushups was always positive. And there was no way that I was going to come into this thread and post a table where I hadn't done my part if possible. I totally agree that if one is injured or feeling bad from doing pushups, see a doctor. Pushups are good, but the brain is better at being a little brat sometimes.
Well I agree with you and in my own opinion If you are going to do push-ups every day, having a standard exercise system is important. If only practiced without technical correction, the movement can also lead to serious injuries. For example, you can experience lower back pain or shoulder pain if you don't do push-ups properly. Wrist Injuries: Push-ups often affect the wrists a lot, if you have an injury or have ever injured this position, consider seeing a physiotherapist before performing the movement. Your doctor may suggest you switch to dolphin pushups (i.e., doing push-ups with your forearms instead of your hands). It is always advisable to check your fitness status and talk to your doctor (health professional) before starting a new exercise routine.
So it is advised to do push ups properly, if you think you can't learn how to do it properly from YouTube I think you can visit the gym center the instructor will help you on that.
