I have found that if I immediately change out of my work clothes and into my workout gear, I am more likely to exercise. There is so much to do when I walk in the door. I have to check the kids' homework, sign their homework sheets, and listen to their fun stories about school. Pets need to be taken care of, dinner plans need to be started, laundry put in the washer, and the list goes on... You get the idea.
I'm so wiped out after a hard day at work and taking care of my family in the evening that I can easily find an excuse not to workout. In the past, I would even say I was too tired to change clothes to workout. Pathetic - I know.
I have taken one of those excuses out of the equation by changing my clothes first thing. Then I take care of everyone else. It is several hours later before I actually workout but having the gear on makes it easier to get moving. Get your gear on!
