Muscle pain normal at first. Just don't overdo it the first few days. :)

yes we don't go for nothing but 3 quarters of an hour. But I had done pullups I just couldn't do it anymore. And there I tried too hard. but you are right to build up calm, it must remain fun and you must be able to keep it up

Yup. Always keep it fun. It is one of the benefits of going to a gym where there are a lot of person. 🙂
