Stiffness

Stiffness: the quality of being firm, hard or unable to bend.

According to the Cambridge Advanced Learner's Dictionary, feeling stiffness on a muscle implies that you can't move it. I agree with that. It is almost an hour I have finished my aerobics class and I can't move my legs yet. The teacher has been particularly hard today. We have run ourselves into the ground!

We have been doing exercise for an hour and one can say : "It's not that bad". In fact, it's not that bad but I'm not used to do such intense exercises because the teacher we had before this one made more relaxed classes.

The truth is that I prefer this ones because when I finish the class I feel better; I feel new (Well, tired, but new). Thanks to sweat, your body eliminates substances that it doesn't need and that is why you feel revitalized. The best way to do that is doing exercise.

Doing exercise is also good for relaxing and helps to being concentrated. So, although I know that tomorrow I couldn't move myself, I feel good and happy for having done that aerobics class.
