Is it normal to not be able to do a push-up?
Mostly.Normal for most people
Yes, it’s normal to struggle with a push-up or not be able to do one yet. Push-ups take upper-body and core strength, and plenty of people need to build up to them.
A push-up looks simple, but it asks your chest, shoulders, arms, and core to move a good chunk of your body weight. Your strength, experience, and even body proportions can all affect how hard it feels—so not managing one isn’t a character flaw or a fitness verdict.
