I love that on the fitbit website it will graph your active score, or calories burned, steps taken, and floors climbed. I usually will have the website open at work and try to get up and talk a walk or something if I have had grey for an extended period of time.
I've started doing two small things that have helped me feel better and clear my mind so I can work better. I've found that these things are also quite enjoyable. The first thing that I have started doing, is going on little walks. One around 11 and one around 3pm. The first one is a determined course and is usually somewhat brisk. For the afternoon one, I like to wander and just enjoy finding random little things or think about random things. I find this really relaxing. The other day I went on a walk and found the following in a random field. It made me smile. So random.
After work the other day, I took a simple walk in the foothills behind where I work. It was a beautiful walk and easy however, I was surprised at how many calories it burned. These things are so enjoyable, but it's just a matter of getting up and starting. The other thing that I have been doing is, every time I go to fill up my 1 liter water bottle I go all the way up the stairs and all the way back (about 3 floors). It is nice.
1. Last thing. So on MFP I added some random people for motivation or for inspiration. One of the guys that I friend-ed was super nice and informed me about a couple things in regard to weightlifting. One of the things that he sent me was in regard to workouts for knee pain. I thought I would share the article in case I need to reference it again. Thanks! http://www.t-nation.com/free_online_article/most_recent/singleleg_training_modifications_for_knee_pain
