Pushups build muscle but do not build strength or stamina. Here is why pushups are not a good option for building a strong chest.
First of all, pushups are a very low impact exercise and therefore can be done from all angles. You can pushups in all possible positions and all possible ways. This means that you cannot take a specific position, make specific postures, and expect to get very strong and effective results.
Your hands are well supported by the bar. The bar passes in and out of your body with no effort. That means that all that happens when you are pushing yourself up to a certain height is your feet slipping off the floor, your arms getting tired, and your chest collapsing.
Second, pushups have many different variations, so many that the very basic exercise of holding the bar up and extending your arms is quite different from a lot of other exercises. So what happens when you do this?
Your arms and legs are not a great muscle builder. They don’t work on their own or with any other muscle groups. They only increase the size of the muscle fibers that are in your arms and legs. So they are not going to build a big chest.
So the big chest is not the result of adding big muscles to your arms and legs. It is the result of working your chest using those larger muscle groups. If you are smart about your pushups, you will be doing a lot of pushing instead of lifting. That means you will be doing the work but your triceps and forearms will be working hard, too.
Pushups, however, can be very effective in developing your biceps. That’s the short answer. Let’s talk a little bit about the long answer.
There are many reasons to build new muscles. That is, after all, the point of exercises like pushups. One reason is to get stronger, another reason is to gain the endurance to go on. And, of course, the third reason is to be able to do more things.
Pushups have two advantages over other types of exercises. They are low impact, so that you can go ahead and do them almost anywhere, and they are exercises that require little or no recovery. That means you can do as many pushups as you want and do them until you can’t stand up.
That means a good short answer to the question: Do pushups build muscle is that they are an effective resistance workout. It also means that it is easy to see how they can work the biceps very effectively.
Building a big chest takes a combination of several exercise techniques. The basic exercises alone will not do the job. What you need is something else, such as pullups or dips, and then something else, such as the barbell bench press. All three of these things can help you build a big chest.
Pushups are a useful exercise, but they should not be the only thing you do to build muscle. For that, there are better alternatives. Look at the alternatives to pushups, and consider how the basic pushup could have been done differently to make them better.
