 hey, okay, I don't need to warm up, let's go, then I'm not going to get anything from that. So my mental capability to perceive this is going to hurt, it's going to be hot, I'm going to be sweaty, I'm going to be whatever, the more I feel that, the more intense the anticipated workout is, therefore, the more benefit I'm going to get from it within reason. And I've been working out forever, so I don't have a problem with heart and, you know, pull muscles, and I just don't even walk in that world.
