Second and third debate

Second debate: when my mother knew that we were training crossfit in the school she started to wonder if she could do it too. I showed her what we were doing and she started to be jelous because she'd like to practise this kind of sport too. When I realised that she was watching Crossfit videos on YouTube I started to worried. I didn't know how her body was going to react to this type of exercise, so I throw a question by Twitter

Third debate: my friend Ana wanted to know the origin of crossfit and I knew the answers :)
