I went to the gym for the first time two days ago with some friends that have been doing it a while. I did various arm exercises, lifted a 45 pound bar, did some sit ups where you catch a ball from the partner and throw back to him. This one weird double rope that you pull down and split it. Anyways.. I am really sore... is it normal? Like even putting on my jacket sucks and my stomach feels tight. I want to get in a routine but I'm afraid I'm gonna hurt myself... I'm 27, 6 feet tall, and 155 pounds.
