As a personal trainer, I feel like I am constantly moving. I'm demonstrating a movement, or I'm picking up weights to give to my clients, or, sometimes, I'm doing a bear crawl with them. I also find time to move for my own benefit. Running, swimming, cycling, or my own workouts. By the end of the day, when I get to slow down, it feels magical.
In our modern world, we wear busy-ness as a badge of honor. How often do we find ourselves in a conversation in which we are listing all the things we have to do? Who we have to drive to what practice? Laundry, food shopping, work, life....
I rarely hear people say "Today I spent an hour reading" or "Today I took 30 minutes and watched traffic go by" without adding something about being lazy, or a slacker. We feel the need to make an excuse for being un-busy.
If you are an athlete, or exercise regularly, it is important to give your body a break. And not only when it is telling you to do so (through pain or other such sensation), but rather before your body tells you it needs a break. Make sure that you schedule a day without exercise in order for your body to reset. Make sure you fuel your body in a way that allows it to have enough fuel to not only do your workout, but to recover from it.
As I write this, I'm recovering from a cold that knocked me on my butt. Sometimes your body not only talks to you, but forces you to listen.
