You took the first step...remember those baby steps!
Did you set your clothes out the night before? Were your sneakers accessible so you could slip right into them? I can't tell you how much that helps me to be consistent. The less you have to think about first thing in the morning the better, and the more likely you'll be to just do it.
On a previous post, I wrote about developing the habit of exercise so that it simply becomes a part of your daily routine...sort of like brushing your teeth. Try to be consistent but if you miss a day, don't beat yourself up about it. Just get back on schedule the next day. It takes 21 days to form a habit and 100 days for it to become automatic. So, make a commitment to continue at least three weeks and... you may find yourself looking forward to those morning walks.
I've found that music is a great way to keep me motivated during exercise. Having a quick tempo keeps your body moving quickly. It's also a great distraction if you're finding it difficult to keep going. Think of the theme song to the Rocky movies.
Keep your eyes on your goal. Are you trying to lose weight? Or are just trying to stay healthy or have more energy?
I have two pictures I keep posted in my office of how I want my stomach to look; you know those six pack abs! It helps me to keep one of my goals in mind.
You might consider taking a picture of yourself now and then another in six weeks. If you're trying to improve your blood pressure or cholesterol readings, it's great to chart your progress with new readings. Improved results will help to keep you motivated and on track.
If you started walking yesterday, I hope you'll post a comment and let me know so I can encourage you.
