Don, I know exactly what you mean. I'm always really energetic towards the beginning of the week because Monday is my rest day, but towards Thursday or Friday I start doggin' it because I'm getting tired.
Had to pop in real quick. I just had my first 'bad' experience at the gym. I took a pilates class this morning on a whim and there was this girl there who was just....staring at me. Venomously. Now, I've been going long enough that I've gotten passed the 'everyone is looking at me' phase. This girl was seriously giving me the evil eye. I could practically read her mind as she sat there thinking, "Why is this fat whale even bothering to blubber herself off the ground?" Now, this has been one bad experience thrown in the middle of MANY good ones, but it kind of hit something home for me. I have a thick enough skin that I don't let stuff like that bother me much, but not everyone does. People wonder why fat people stay fat and that's part of the reason. It's already hard enough to get in shape in general, but to honestly feel like someone there is displaying blatant animosity towards you? That's why a lot of people quit. Every time I see soemthing like that, it takes everything in me not to say, "What the hell is wrong with you? I'm trying to make a positive change and you would judge me for that? &$@! off!"
