If you start out and are having difficulty doing a pull up there are a few things you can do. You can grab a partner to spot you at the waste to assist you in doing a pull up or you can grab a chair to take off some of the added weight causing you problems. Once you begin to strengthen the muscles you can then get rid of the chair or partner and do them on your own.
