2 year old🤪

Okay so I need some advice. I have a 2 year old daughter(she’s very advanced for her age) here for the past month she hasn’t been listening, she always telling me and her dad no, doing things that she knows she’s going to get in trouble for.. I want to put her into gymnastics or something fun for her to do but I’m scared about her behavior. I understand that she’s 2 and that this happens. But it’s an everyday thing. I’ve tried spanking(which I hate doing) and I’ve tried sitting her down and calmly talking to her but nothing has helps. Can someone please give me some advice as to how you get your little one to listen.
