So recently I have had zero time to workout. I've come to conclusion I will just work in more activity during the day....like doing squats when studying or folding laundry, walking on the treadmill if I have to read a chapter, walking in place in the check out line and parking further away when I am running errands (which since I got a new car I am really ok with that lol).
I said something about that to someone and they tried to guilt me into doing more. I get up at 5:30am every morning during the week and do not stop until I go to bed around 10pm. There is no way I'm getting up earlier to workout if its going to cause me to not be my best for the rest of the day. My summer classes are condensed, 8 weeks of school and covering 16 weeks worth of material, and to me that is most important right now. That and my family. Oh and keeping my eating in check, which I have been doing marvelously ;)
Cut yourself some slack, I know I am. I know I will do more when I am able and that is ok.
Sometimes you just have to do what you can, with what you have, where you are. Do not let people make you feel like you are inferior because you take a step back or start something but you aren't going "balls to the wall" with it.
How to incorporate more activity? Here are some more examples I found at http://www.healthcentral.com/diet-exercise/mood247_include-31639-5.html
Get up and get moving! :)
